Suppose there is a 21.9% probability that a randomly selected person aged 20 years or older is a jogger. In addition, there is a 21.9% probability that a randomly selected person aged 20 years or older is female, given that he or she jogs. What is the probability that a randomly selected person aged 20 years or older is female and jogs? Would it be unusual to randomly select a person aged 20 years or older who is female and jogs? The probability that a randomly selected person aged 35 years or older is female and jogs is Would it be unusual?
A. No
B. Yes

The value

The answer is No

Step-by-step explanation:

From the question we are told that

The probability a person is a jogger is

The probability that a person is female given that she jogs is

Generally the probability that a randomly selected person aged 20 years or older is female and jogs? Would it be unusual to randomly select a person aged 20 years or older who is female and jogs is mathematically represented as

=>    

=>    

Given that the probability is  equal to 0.05 then it is not unusual
