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, ho
w many times could Jorelle expect to pick the letter tile "E"?
Since there are a total of 5 letter tiles in the box, and each letter tile has an equal probability of being picked each time, Jorelle can expect to pick the letter tile "E" roughly 20% of the time (1 out of 5). Therefore, out of 100 picks, he could expect to pick the letter tile "E" approximately 20 times.
