Transcribed Image Text:Suppose that the probability that a college student orders groceries online is
0.60 in a week, and we select 5 random college students. You may assume
that ordering groceries online for each student in each week is independent,
and that the probability of ordering groceries is the same for all students in all
weeks. A partial distribution for 5 students follows:
