The probability that a man will be alive in 10 year is 0.8 and the probability that his wife will be
alive in 10 years is 0.9 Find the probability that in 10 years Both will be alive; Only the man will
be alive; Only the wife will be alive; At least one will be alive.
Solution
(a)
P = 0.8*0.9 = 0.72
(b)
P = 0.8*(1-0.9) = 0.08
(c)
P = (1-0.8)*(0.9) = 0.18
(d)
P =1- (1-0.8)(1-0.9) = 1-0.02 = 0.98.
