The table lists the probability of Amy, Susan, Mark, Nina, and Jeff studying on a Sunday. Also, the average number of hours each studies is given.

Amy Susan Mark Nina Jeff

Probability: 0.23 0.31 0.17 0.19 0.10

Average Number

of Hours of Study:2.5 1.5 3 2 4.5

If you select 10 Sundays from the school year at random, who is likely to have studied the most hours overall?

a. Amy

b. Susan

c. Mark

d. Nina

e. Jeff

Amy: 2.5 hours * 10 sundays = 25 hours * 0.23 probability = 5.75 hours

Susan: 1.5 hours * 10 Sundays = 15 hrs * 0.31 probability = 4.65 hours

Mark: 3 hours * 10 Sundays = 30 hours * 0.17 probability = 5.10 hours

Nina: 2 hours * 10 Sundays = 20 hours * 0.19 probability = 3.8 hours

Jeff: 4.5 hours * 10 Sundays = 45 hours * 0.10 probability = 4.5 hours

Based on the result of my computation, Choice A.) Amy is likely to have studied the most hours over all with 5.75 hours.
