The probability that client D will be able to live to be 59 years old is 0.4.
<h3>How to calculate probability?</h3>
Youe information is incomplete. Therefore, an overview of probability will be given.
Let's assume that there is an entire population of 50 people and the number of those that lives to 59 years is 20.
Therefore, the probability that can be deduced of those that live to 59 years will be:
= 20/50 × 100
= 2/5 × 100.
= 40%
= 0.4
In conclusion, the probability is 0.4.
