Question

Part B

Answer 1

Using the probability concept, it is found that there is a 0.8456=  84.56% probability that client A lives to be 20 years old.

What is probability?

A probability is the chances of happening of any event from the random variables. A probability is the number of desired outcomes divided by the number of total outcomes, that is:

$P=\dfrac{D}{T}$

In this problem:

Out of 100,000 clients, 84,560 lives to age 64, hence

Then:

$P=\dfrac{84560}{100000}=84.56\%$

There is a 0.8456= 84.56% probability that client A lives to be 30 years old.
