Question

Let 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. Identify the answer which expresses the following with correct notation: The probability that a randomly chosen person exercises regularly, given that the person has low blood pressure.

Answer 1

Answer:

The answer is p(E | B) where p(E | B )  = $\frac{p(E\cap B)}{p(B)}$.

Step-by-step explanation:

The event B is that a randomly chosen person has low blood pressure.

The event E is the event that a randomly chosen person exercises regularly.

Given that a person has low blood pressure we have to find the probability that the person exercises regularly.

This is conditional probability of two events and the probability required can be written as

p(E | B) where p(E | B )  = $\frac{p(E\cap B)}{p(B)}$.
