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
Stells [14]

Answer:

The value P(F\ n \  J) = 0.05

The answer is No

Step-by-step explanation:

From the question we are told that

The probability a person is a jogger is P(J) =  21.9 \% =  0.219

The probability that a person is female given that she jogs is P(F|J)  =  21.9 \%  = 0.219

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

P(F\ n \  J) = P(J)* P(F|J)

=>    P(F\ n \  J) = 0.219* 0.219

=>    P(F\ n \  J) = 0.05

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