Question

Typically, 10% of students make a D on their tests, 60% make a C on their test, and 30% make an A. Mrs. Smith uses a random-number table to find the experimental probability that of 5 students', at least 3 will make a C. The digit 0 represents students who make a D. The digits 1,2,3,4,5, and 6 represent students who make a C. The digits 7,8, and 9 represent students who make an A.

Find the experiment that of 5 students at least 3 will make a C.
A:7/20
B:9/20
C: 11/20
D:13/20

Answer 1

i think its B idk plz help

Answer 2

when you get it can you explain why it is the answer plz

Answer 3

I would think the answer would be D because at least 60% have to make a C. Given the fractions D is the only fraction with higher than 60%.

Mathematically evaluating 3/5 is 60%, 20 is the common denominator in every answer choice. 20 is a multiple of 5, so 20/5 = 4.
Multiply 4 *3 =12

At least 12 students must have a C.

Only answer that fits is D

Answer 57

The answer is A. Start Fraction 1 over 18 End Fraction.

There are a total of 36 possible outcomes when rolling two number cubes. The probability of rolling a 9 is 4 out of 36 since the only pairs that add up to 9 are {3,6}, {4,5}, {5,4}, and {6,3}. Simplifying the fraction gives 1/9. However, the prompt is asking for the probability of rolling a sum of 9, which means 1/9 × 2 = Start Fraction 1 over 18 End Fraction.

Answer 58

The answer is D. 120.

The word TOPIC has five letters. The number of arrangements that can be made by taking all five letters is 5!, which is equal to 120. You can use the factorial notation to arrive at the answer quickly, that is 5! = 5 × 4 × 3 × 2 × 1 = 120.

Answer 59

The answer is C. 220.

For Jason to form his team of 9 players out of a total of 12 players, he can make use of the combination formula. That is, the number of different teams he can form is the number of ways he can select 9 players from 12.

The number of combinations of n objects taken r at a time is given by n C r = n!/[(n-r)!r!].

Therefore, the number of different teams that Jason can form is 12 C 9 = 12!/[(12-9)!9!] = 220.

Answer 60

The answer is B. 6!; 720.


There are 6 seats for you and your 5 friends to sit in. The total number of ways that you can arrange yourselves in those seats is 6!, which is 720.

Factorial notation represents the product of descending natural numbers, beginning with the number itself and ending with the number one. Hence, 6! is written as:

6! = 6 × 5 × 4 × 3 × 2 × 1 = 720

Answer 61

There are 9 tosses and 5 of those times an odd number is rolled. Thus, the experimental probability of rolling an odd number is 5/9 which is option C. Therefore, the answer is C. Start Fraction 5 over 9 End Fraction.

Answer 62

The answer is D. 420.

To select the captain and co-captain, the coach has to choose two people from a group of 20. The number of combinations of two people from a group of 20 is:

20 C 2 = (20 x 19) / (2 x 1) = 190

Therefore, there are 190 ways that the coach can select the captain and co-captain from the group of 20.

Answer 63

The answer is C. 30.

When buying a new dress, you have 3 choices for the length, 5 choices for the color, and 2 choices for the style. The total number of choices is found by multiplying these choices:

3 x 5 x 2 = 30

Therefore, there are 30 different choices for one dress, which is option C.

Answer 64

The answer is D. 59,280.

To solve the problem, first note that there are 40 choices for first place, since any one of the 40 entries can come in first. Next, there are then 39 choices left for second place, since one entry has already received first place. Finally, there are 38 choices left for third place.

Using the multiplication principle of counting, the number of different ways for the entries to finish in first, second, and third place is given by:

40 x 39 x 38 = 59,280

Therefore, there are 59,280 different ways for the entries to finish in first, second, and third place, which is option D.

Answer 65

The answer is C. two over one hundred twenty-one.

When Tyler selects the first tile, there are 13 tiles to choose from in the bag, and only three of them are I's. Therefore, the probability of drawing an I on the first draw is 3/13.

Now, assuming that Tyler did not replace the tile, there are 12 tiles left in the bag with only two I's remaining. This means that the probability of selecting an I on the second draw, without replacement, is 2/12 (or 1/6).

The probability of both events happening is the product of their individual probabilities, which is:

(3/13) x (2/12) = 6/156 = 1/26

Therefore, the answer is 2/121 or option C.

Answer 66

To calculate the number of different sundaes that can be made, we need to count the combinations of four toppings that can be selected from a set of seven. The number of such combinations is given by 7 C 4.

7 C 4 = (7!)/(4!(7-4)!) = 35

Therefore, there are 35 different sundaes that can be made with four toppings, which is option A.

Answer 67

The probability of picking a $5 bill is given to be 1/3.

Let P($10) be the probability of picking a $10 bill and P($20) be the probability of picking a $20 bill.

We know that P($10) = 4/15. The combined probabilities of picking $5, $10 or $20 bill should add up to 1. Therefore:

1 = P($5) + P($10) + P($20)

We know that P($5) = 1/3. We can rearrange the above equation to solve for P($20):

P($20) = 1 - P($5) - P($10)
= 1 - 1/3 - 4/15
= 1 - 5/15
= 10/15
= 2/3

Therefore, the probability of picking a $20 bill is 2/3 which is option D.

Answer 68

There are 36 possible outcomes when two number cubes are rolled. To find the probability that the roll will result in both numbers being the same, you need to count the number of outcomes where the numbers are the same.

There are 6 possible outcomes where both numbers are 1, 6 outcomes where both numbers are 2, and so on up to 6 possible outcomes where both numbers are 6. Therefore, there are 6 + 6 + 6 + 6 + 6 + 6 = 36 outcomes where both numbers are the same.

The probability of rolling the same number on both cubes is then:

P(same number) = number of outcomes where both numbers the same / total number of outcomes
= 36 / 36
= 1

Therefore, the probability that the roll will result in both numbers being the same is 1 or 100%, which is not one of the answer choices that were provided. Based on the options provided, the closest answer would be A. Start Fraction 1 over 6 End Fraction.
