Given that B be the event that a randomly chosen person has low blood pressure. Let E be the event that a randomly chosen person exercises regularly.

The probability that a randomly chosen person exercises regularly, given that the person has low blood pressure___________

This is the conditional probability for E given that B has occurred.

We know that prob for A given B has occurred is represented by

P(A/B)

Hence under the same rule we have

The probability that a randomly chosen person exercises regularly, given that the person has low blood pressure___________P(E/B) = P(EB)/P(B), provided P(B) ≠0
