Question

the probability that 50 years old man will live till 60 is 0.53 n the probability that a 45 year old woman will be alive till 55 is 0 87. what is probability that man is 50 n woman is 45 have at least one will be alive 10yrs hence.​

Answer 1

Step-by-step explanation:

The probability that both will be alive for 10 years hence,

i.e, the probability that the man and his wife both will be alive 10 years hence is

0.83×0.87=0.7221.

The probability that at least one of them will be alive is

1−P {That none of them remains alive 10 years hence }

=1−(1−0.83)(1−0.87)=1−0.17×0.13

=0.9779
