Jesse randomly selects a letter from the word TRIAL. The probability of selecting the letter T each time is 15

or 20%. If the experiment is repeated 140 times, how many times will Jesse expect to select a T? Use the lesson notes as needed for help.(1 point)

[AI-generated answer — Bot GPT 3.5]

To find the number of times Jesse expects to select a T, we can multiply the probability of selecting a T by the total number of times the experiment is repeated.

Expected number of T selections = probability of selecting T * total number of trials
Expected number of T selections = 0.20 * 140
Expected number of T selections = 28

Therefore, Jesse expects to select the letter T 28 times out of 140 trials.
