Q30 of 249 Page 31

Mark the correct alternative in each of the following:
If P(A) = 3/10, P(B) = 2/5 and P(A ∪B) = 3/5, then P(A/B) + P(B/A) equals

P(A) = , P(B) = , P(A⋃B) = → (Given)

According to the addition theorem of probability for two events A and B we have,

P(A) + P(B) – P(A⋂B) = P(A⋃B)

Now then,

Mark the correct alternative in each of the following:

If A and B are two events associated to a random experiment such that and P(B) = 17/20, then P(A/B) =

Mark the correct alternative in each of the following:

Associated to a random experiment two events A and B are such that P(B) = 3/5, P(A/B) = 1/2 and P(A ∪B) = 4/5. The value of P(A) is

Mark the correct alternative in each of the following:

Let P(A) = 7/13, P(B) = 9/13 and P(A ∩ B) = 4/13. Then

Mark the correct alternative in each of the following:

If and then is equal to

Mark the correct alternative in each of the following:If P(A) = 3/10, P(B) = 2/5 and P(A ∪B) = 3/5, then P(A/B) + P(B/A) equals
