Of the 538 people who had an annual check up, 215 had high blood pressure.  Estimate the  probability that the next person who has a check up will have high blood pressure.  show work

Hello!

Because we know nothing about the next person, it can be assumed random.

We know the experimental probability: 215/538 to have high blood pressure.

215/538 = approx. 0.400. or 40%.

Please ask if something is unclear.
