4. At a college, 60 percent of the students are female and 35 percent of the students receive a grade of C. About 40 percent of the students are female and "not C" students. Use this contingency table.

_

- Gender\Grade - C - Not C or C - ?

- Female (F) - ? - 0.40 - 0.60

- Male (M) - ? - ? - ?

- ? - 0.35 - ? - ?

If a randomly selected student is a "not C" student, what is the probability the student is a male student?

5. A and B are independent events. Moreover, P(A) = 0.8 andP(B) = 0.6. Determine P(A B), that is,P(A or B)

6. A lot contains 12 items and 4 are defective. If two items are drawn at random from the lot, without replacement, what is the probability there is exactly one defective?(Hint: You have to use both Multiplication and Addition rules)
