Which choice correctly describes this event? I will pull a blue marble at random out of a jar with 49 red marbles and 1 blue marble

A likely

are thay both likely

The first event is unlikely because there is only 1 blue marble out of 50 marbles in the jar. The second event is likely because there are 3 out of 6 possible outcomes (1, 2, or 3) that result in the desired outcome.

Which choice correctly describes this event? I will draw two cards out of a standard deck of playing cards, and they will be 2 Kings.

You roll a six sided number cube (die). What is the BEST answer for the probability that the number rolled is between 1 and 6, inclusive?

Responses
A impossibleimpossible
B certaincertain
C very likelyvery likely
D unlikelyunlikely

B certain. Since the number cube has six sides, each side has an equal probability of being rolled. Therefore, the probability of rolling a number between 1 and 6, inclusive, is 100%.

What is the BEST word to describe the probability that the spinner will stop on 3 or 4?

D Very likely.

will the numbers are 1 2 3 3 3 4 4

In that case, the probability of the spinner stopping on 3 or 4 would be greater than if the spinner had an even distribution of all the numbers from 1 to 4. However, without knowing the total number of sections on the spinner, it is not possible to calculate the exact probability.

C unlikely. Since there is only one section labeled 1 and one section labeled 2 out of a total of 7 sections, the probability of the spinner stopping on 1 or 2 is low.

Place the events in order of increasing likelihood.

A. Landing on the number 33 on a spinner with 100 numbers.
B. Rolling a sum of 13 on a roll of two dice.
C. Drawing a black card from five decks of cards.
D. Drawing a red or black card from a deck.
Responses
A D < C < A < B
B A < B < C < D
C B < A < D < C*
D B < A < C < D
am i right

No, the correct order is B < C < D < A.

The probability of rolling a sum of 13 on a roll of two dice is very low, making it the least likely event.

Drawing a black card from five decks of cards has a higher probability compared to rolling a sum of 13, but the chance is still relatively low.

Drawing a red or black card from a deck is more likely to occur than drawing a black card from five decks because there are only two possible outcomes instead of five.

Landing on the number 33 on a spinner with 100 numbers is the most likely event because there are 100 possible outcomes, giving a higher chance of landing on 33.

there are only

A D < C < A < B
B A < B < C < D
C B < A < D < C
D B < A < C < D

The correct answer is D.

Which THREE statements are correct when determining the likelihood of a chance event occurring?

Responses
A A chance event with a 0.35 probability is more likely to occur than an event with a 0.40 probability.A chance event with a 0.35 probability is more likely to occur than an event with a 0.40 probability.
B The closer the probability of a chance event is to 0, the less likely it is for the event to occur.The closer the probability of a chance event is to 0, the less likely it is for the event to occur.
C A probability of 12
means the event will more than likely occur.A probability of 1 2 means the event will more than likely occur.
D A chance event with a probability of 0.68 is more likely to occur than an event with a 0.55 probability.A chance event with a probability of 0.68 is more likely to occur than an event with a 0.55 probability.
E A chance event with a 0.95 probability of occurring is likely to occur.

A, B, and D.

A lower probability means that the chance event is less likely to occur than an event with a higher probability. Hence statement A is incorrect.

The closer the probability of an event is to 0, the less likely it is for the event to occur. So statement B is correct.

A probability of 1/2 means that the event is equally as likely to occur as not to occur. So statement C is incorrect.

A higher probability means that an event is more likely to occur than an event with a lower probability. Hence, statement D is correct.

Statement E is incorrect because a probability of 0.95 means that the event is nearly certain to occur.

are you shure

Yes, I'm sure. A probability of 0.95 is very high, almost certain that the event will occur. Therefore, statement E is incorrect.

are you shure its abd

Yes, I'm sure. The statement "A chance event with a probability of 0.95 is likely to occur" is not correct, because the probability of 0.95 is very high, almost certain that the event will occur.

you are rong :( :(

I apologize for the confusion. Statement E is correct because a probability of 0.95 is a very high probability, meaning it is likely that the event will occur.

Suppose a bag contains 30 white marbles, 10 purple marbles, and 8 green marbles.

One marble is randomly selected from the bag. In this situation, the probability of 1 could represent which event?
A not selecting a yellow marblenot selecting a yellow marble
B selecting a white marbleselecting a white marble
C selecting either a white or purple marbleselecting either a white or purple marble
D selecting a green marbleselecting a green marble

Which BEST describes the probability of selecting a purple marble?
A ImpossibleImpossible
B LikelyLikely
C CertainCertain
D Not likelyNot likely

A. The probability of not selecting a yellow marble (#1) is correct because there are no yellow marbles in the bag.

B. The probability of selecting a white marble is (30/48) = 0.625 or 62.5%, since there are 30 white marbles out of 48 total marbles in the bag. So this is not the answer to the question of which event has a probability of 1.

C. The probability of selecting either a white or purple marble is (30 + 10)/48 = 0.833 or 83.3%, since there are 30 white marbles and 10 purple marbles out of 48 total marbles in the bag. This is not the answer to the question of which event has a probability of 1.

D. The probability of selecting a green marble is (8/48) = 0.167 or 16.7%, since there are 8 green marbles out of 48 total marbles in the bag. This is not the answer to the question of which event has a probability of 1.

Therefore, the correct answer to the first question is A.

The probability of selecting a purple marble is (10/48) = 0.208 or 20.8%, since there are 10 purple marbles out of 48 total marbles in the bag. This is not a certain or unlikely event, so the correct answer to the second question is D. Not likely.

Julie conducts an experiment to find the average word length in a book for a 4th grader and a book for a 8th grader. She finds that for the fourth grade book the mean word length is 5 letters with a range of 6 and for the 8th grade book the mean word length is 6 letters with a range of 9. Which statement is true?

Responses
A The word length varies more in the 4th grade book than the 8th grade book.The word length varies more in the 4th grade book than the 8th grade book.
B On average, the book for the 8th grader has longer words.On average, the book for the 8th grader has longer words.
C The longest word in the book for the 4th grader is longer than that in the 8th grade book.The longest word in the book for the 4th grader is longer than that in the 8th grade book.
D The longest word in the 8th grade book contains 15 letters.The longest word in the 8th grade book contains 15 letters.

A. The statement "The word length varies more in the 4th grade book than the 8th grade book" is true because the range of the word length is larger for the 4th grade book than for the 8th grade book.

B. The statement "On average, the book for the 8th grader has longer words" is true because the mean word length for the 8th grade book is 6 letters, which is longer than the mean word length of 5 letters for the 4th grade book.

C. The statement "The longest word in the book for the 4th grader is longer than that in the 8th grade book" is false because the range for the 8th grade book is 9, while the range for the 4th grade book is 6. Therefore, it is possible that the longest word in the 8th grade book is longer than the longest word in the 4th grade book.

D. The statement "The longest word in the 8th grade book contains 15 letters" cannot be determined based on the given information, as the range of the 8th grade book is 9, so it is possible that the longest word could be up to 9 letters long, but it could be shorter than 15 letters.

witch one is true

Statements A and B are both true based on the given information. Statement C is false, and statement D cannot be determined.

i can only pick 1 so A or B

If you can only pick one, then the best answer is B because it is also a correct statement and provides additional information about the average word length of the books.

are you Shure?

Yes, I am certain that B is a correct statement based on the given information.

ok thank you

You're welcome! Do you have any other questions or is there anything else I can assist you with?

At a pet store, the lizards in aquarium A have a mean length of 13 cm and a range from 9 cm to 15 cm. In aquarium B, the lizards have a mean length of 15 cm and a range from 14 cm to 17 cm. Which statement BEST compares the lizards in the two aquariums?

C On average, the lizards in aquarium A are longer.On average, the lizards in aquarium A are longer.
D Aquarium A has the longest lizard at this pet store.

A. The statement "The lizards in aquarium A vary in length more than aquarium B" is true because the range of the lizard length in aquarium A is 6 cm (15 cm - 9 cm), which is larger than the range in aquarium B of 3 cm (17 cm - 14 cm).

B. The statement "The lizards in aquarium B vary in length more than aquarium A" is false because the range in aquarium A is larger than the range in aquarium B.

C. The statement "On average, the lizards in aquarium A are longer" is false because the mean length for aquarium B is 15 cm, which is longer than the mean length of 13 cm for aquarium A.

D. The statement "Aquarium A has the longest lizard at this pet store" cannot be determined based on the given information.

Therefore, the best answer is A - "The lizards in aquarium A vary in length more than aquarium B."

D On average, the middle school boys are taller.On average, the middle school boys are taller.
Skip to navigation

C. The statement "The middle school boys vary in height more than the high school boys" is correct because the range of the middle school boys' heights is smaller (5 cm) than the range of the high school boys' heights (8 cm).

A. The statement "Half of the high school boys are between 181 cm and 183 cm in height" is incorrect, as the range of the high school boys' heights is 8 cm, so half of that range would be 2 cm, meaning half of the high school boys are in the range of 177.5cm to 180 cm.

B. The statement "For these groups, every high school boy is taller than every middle school boy" is incorrect, since the ranges for the two groups overlap and there could be middle school boys taller than some high school boys.

D. The statement "On average, the middle school boys are taller" is incorrect since the mean height for the high school boys is 180 cm while for the middle school boys it is 167 cm.

Therefore, the best answer is C - "The middle school boys vary in height more than the high school boys."
