If the probability that A will live 15 years is 7/8 and that B will li...
Given, P(A lives 15 years) = 7/8
P(B lives 15 years) = 9/10
We need to find the probability that both A and B will live after 15 years.
Solution:
Let's assume that events A and B are independent, i.e., the survival of A does not affect the survival of B and vice versa.
Then, the probability that both A and B will live after 15 years can be calculated as follows:
P(A and B live after 15 years) = P(A lives 15 years) × P(B lives 15 years)
= (7/8) × (9/10) = 63/80
Therefore, the probability that both A and B will live after 15 years is 63/80.
Answer: Option B.
P(B lives 15 years) = 9/10
