The letter tiles are placed in a box. Without looking, Jorelle picks a
letter tile from the box and records the result before placing it back. If he repeats the procedure 100
times, how many times will the letter tile be picked?(1 point)
11 answers
Since Jorelle is placing the tile back after each pick, the number of times the same letter tile can be picked is unlimited. Therefore, the letter tile can potentially be picked all 100 times.
wrong
I apologize for the oversight. Since the letter tiles are placed back in the box after each pick, the same letter tile can be picked multiple times. Therefore, the letter tile can be picked any number of times between 0 and 100. The exact number of times the letter tile will be picked cannot be determined without additional information.

There are typically 5 vowels in the English alphabet (a, e, i, o, u) out of a total of 26 letters in the alphabet.
Therefore, the probability of Abby picking a vowel is 5/26 when picking a letter tile randomly from the box.
Therefore, the probability of Abby picking a vowel is 5/26 when picking a letter tile randomly from the box.

You mentioned that part of the information is missing. It seems like the sample space and the probability are not provided. Please provide the missing information so I can help you calculate the probability of picking the number 2 or 3.
Mr. Lim has a bag with some marbles colored red, yellow, green, blue, and white. The marbles are

identical in number. If there are 40 marbles in the bag, how many marbles of each color are in the
bag?(1 point)
If there are 40 marbles in the bag and the marbles of each color are identical in number, the number of marbles of each color can be calculated by dividing the total number of marbles by the number of colors.
Number of marbles of each color = Total number of marbles / Number of colors
Number of marbles of each color = 40 / 5
Number of marbles of each color = 8
Therefore, there are 8 marbles of each color (red, yellow, green, blue, and white) in the bag.
Number of marbles of each color = Total number of marbles / Number of colors
Number of marbles of each color = 40 / 5
Number of marbles of each color = 8
Therefore, there are 8 marbles of each color (red, yellow, green, blue, and white) in the bag.

Since the marbles are identical in number and there are a total of 40 marbles in the bag with 5 colors, each color has 40/5 = 8 marbles.
In this scenario, the probability of picking a green marble in each trial is 8 out of 40, or 1/5.
Therefore, in 50 trials, Mr. Lim can expect to pick:
Expected number of green marbles = Probability of picking a green marble x Total number of trials
Expected number of green marbles = (1/5) x 50
Expected number of green marbles = 10
Mr. Lim can expect to pick 10 green marbles in 50 trials.
In this scenario, the probability of picking a green marble in each trial is 8 out of 40, or 1/5.
Therefore, in 50 trials, Mr. Lim can expect to pick:
Expected number of green marbles = Probability of picking a green marble x Total number of trials
Expected number of green marbles = (1/5) x 50
Expected number of green marbles = 10
Mr. Lim can expect to pick 10 green marbles in 50 trials.
