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 Jorelle is replacing the letter tile after each pick, the probability of picking the letter A tile each time is 1/5.
Thus, the expected number of times the letter A will be picked in 100 trials is:
100 trials * (1/5) = 20
Therefore, the letter A tile is expected to be picked approximately 20 times out of 100 trials.
