(a) Find the values of aa and bb.(b) Find the probability at least two students order groceries online in a week.(c) Find the expected number of students to order groceries online in a one quarter (12 weeks) for our class size of 130. Suppose that the probability that a college student orders groceries online is0.60 in a week, and we select 5 random college students. You may assumethat 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 allweeks. A partial distribution for 5 students follows:X;14 5P(X;)0.0100.0770.2300.346a b3.2.

(a) Find the values of aa and bb.

(b) Find the probability at least two students order groceries online in a week.

(c) Find the expected number of students to order groceries online in a one quarter (12 weeks) for our class size of 130.

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:
