Seventy percent of kids who visit a doctor have a fever and 21% of kids have fever and sore throats .

What is the probability that a kid who goes to the doctor has a sore throat given that he has a fever?

Respuesta :

The probability that a kid who goes to the doctor has a sore throat given that he has a fever is 30%

How to determine the probability?

The given parameters are:

P(Fever) = 70%

P(Fever and sore throat) = 21%

The probability that a kid who goes to the doctor has a sore throat given that he has a fever is calculated as:

P = P(Fever and sore throat)/P(Fever)

So, we have:

P = 21%/70%

Evaluate

P = 30%

Hence, the probability is 30%
