Of 1232 people who came into a blood bank to give blood, 397 people had high blood pressure. estimate the probability that the next person who comes in to give blood will have high blood pressure.

Probability that the next person who comes in to give blood will have high blood pressure is:

0.3222

Let A be an event

then, P(A)= number of favorable events/total number of events

Here, A: People having high blood pressure

P(A)= number of people having high blood pressure/total number of people

     = 397/1232

     = 0.3222

Hence,  probability that the next person who comes in to give blood will have high blood pressure is:

0.3222
