The letter tiles C, A, R, E, S 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 A tile be picked?
Since each letter tile has an equal probability of being selected, the probability of picking the letter A tile on any one pick is 1/5.
Therefore, out of 100 picks, the expected number of times the letter A tile will be picked is:
100 picks * (1/5) = 20
Therefore, the letter A tile will be picked approximately 20 times out of 100 picks.
