"the probability that a randomly selected person has high blood pressure (the event h) is p(h) = 0.5" "find the probability that a randomly selected person has high blood pressure, given that he is a runner."

0.667 is the probability that a randomly selected person has high blood pressure, given that he is a runner.

Step-by-step explanation:

The following information is missing in the question:

The probability that a randomly selected person is a runner

P(R) = 0.3

The probability that a randomly selected person has high blood pressure and is a runner is 0.2

We are given the following information in the question:

The probability that a randomly selected person has high blood pressure is 0.5

P(H) = 0.5

P(R) = 0.3

We have to find the probability that a randomly selected person has high blood pressure, given that he is a runner.

0.667 is the probability that a randomly selected person has high blood pressure, given that he is a runner.

correct answer:

b.(19,-2)

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
