The probability that a man lives after 10 years is 1/4 and that his wife is alive after 10 years is 1/3. The probability that neither of them is alive after 10 years is?

Question

Accepted Answer

P(M) = 1/4; P(W)= 1/3 ⇒ P (M) = 1 - 1/4 = 3/4 ⇒ P(W)= 1 - 1/3 = 2/3 Reqd. probability = P(M) P(W) = 3/4 x 2/3 = 1/2
