The letter tiles C, A, R, E, S are placed in a box. Without looking, Jorelle picks a letter tiles from the box and records the result before placing it back. If he repeats the procedure 100 times, how many times will the letter A tile be picked?

1 answer

Since there are 5 different letter tiles in the box (C, A, R, E, S), the probability of picking the letter A tile on any single draw is 1/5.

Therefore, if Jorelle repeats the procedure 100 times, the expected number of times the letter A tile will be picked is:

100 x 1/5 = 20 times

Therefore, the letter A tile will be picked approximately 20 times out of 100 draws.
