Question

Since the beginning of the year, 1982 people have come into a blood bank to donate blood and 340 were found to have high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure.

Answer 1

Answer:

0.1715

Step-by-step explanation:

From previous experience 340/1982 is the past probability that a person has high blood pressure.

The division of that leads to 0.1715 that the next person will have high blood pressure. That number is roughly (very roughly) 1 person in 6. So if 6 people come in 1 will have high blood presure.
