The probability that a randomly selected person has high blood pressure (the event H) is P (H) = 0.3 and the probability that a randomly selected person is a runner (the event R) is P (R) = 0.5. The probability that a randomly selected person has high blood pressure and is a runner is 0.2. Find the probability that a randomly selected person is a runner, given that he has high blood pressure.

    Answer: 2/3 = 0,67

    Step-by-step explanation: We have P (H) = 0,3 and P (R) = 0,5.

    P (High blood pressure and runner) = P (H∩R) = 0,2

    The problem asks for P (runner, given he has high blood pressure) = P (R|H). This conditional probability is given by the formula:

    P (A|B) = P (A∩B)

    P (B)

    In this case, P (R|H) = P (H∩R) = 0,2 = 2 = 0,67

    P (H) 0,3 3
