Explanation / Answer
Answer to the 18th Question:
18.
P( A int B) = .50
Can P(A) = .20?
A.
only if P(A|B) = .10
P(A int B)/P(B) = .10
.50/P(B) = .10
P(B) = .5/.1 = 5 < which is not possible>
B.
P(B) = .30
P(A int B) = .50
P(A) = .20 ?
Impossible, since intersection itself is .5 therefore A and B should be atleast > .5
C.
False. P(A int B) should be = P(B int A)
D.
TRUE. P(A)=.2<.5, then P(A int B) !=.50
