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? 0.241.20.150.35

Answer 1

Given:

• Probability person A will be alive for 30 years = 0.7

,

• Probability person B will be alive for 30 years = 0.5

Let's find the probability they will be alive for 30 years.

These are independent events.

To find the probability that they will both alive for 30 years, we have:

P(they will both be alive) = P(A will be alive) x P(B will be alive).

Thus, we have:

P(they will both be alive for 30 years) = 0.7 x 0.5 = 0.35

Therefore, the probability they both will be alive for 30 years will be 0.35

• ANSWER:

0.35
