Question

If the probability that the person A will be alive for 30 years is 0.7 and the probability that the person B will be alive for 30 years is 0.5, what is the probability that they both will be alive for 30 years?

0.24
1.2
0.15
0.35

Answer 1

`0,35`

Explanation:

In view of the fact that our events are independent of each other, we should multiply their probabilities:
`P(A \cap B) = P(A) * P(B) = 0,7 * 0,5 = 0,35`.
