PA 061 PB 039 PA B 075 PA B PA PB 38 PA B 716 PA B 1

P(A) = 0.61 P(B) = 0.39 P(A B) = 0.75 P(A B) = P(A) = P(B) = 3/8 P(A B) = 7/16 P(A B) = 1/16 P(A) = 5/16 P(B) = P(A B) = 3/4 P(A B) = 0

Solution

16.

P(A n B) = P(A) + P(B) - P(A U B) = 0.61+0.39-0.75 = 0.25 [answer]

17.

P(A n B) = P(A) + P(B) - P(A U B)

1/16 = P(A) + 3/8 - 7/16

Thus,

P(A) = 1/8 [answer]

18.

P(A n B) = P(A) + P(B) - P(A U B)

0 = 5/16 + P(B) - 3/4

Thus,

P(B) = 7/16 [answer]
