Respuesta :

To approximate the required probability, we will do as follows:

Consider the equivalent question as follows: if we pick one person from this group at random, what is the probability that that person is a female and exercises for at least 30 minutes?

This number can be calculated by simply dividing the total number of females that exercise more than 30 minutes by the total number of people.

That is
