Probability of Population
A research study indicates that 16% of the total population are more than 70 years old. Of those more than 70 years old, 65% have a measurable hearing defect.
Find the probability that a person chosen at random from the population is more than 70 years old given that the person has no measurable hearing defect.
(Round off your answer to 2 decimal places)
The answer is 0.18.

P(More than 70 years old)=16%
P(More than 70 years old that has no measurable hearing defect)=1-(65%)(16%)=89.6%
P(More than 70 years old|The person has no measurable hearing defect)=(16%)/(89.6%)
