Question

Of 1308 people who came into a blood bank to give blood, 314 people had high blood pressure. estimate the probability that the next person who comes in to give blood will have high blood pressure (to 3 decimal places).

a. 0.250
b. 0.490
c. 0.240
d. 0.160

Answer 1

To determine the probability that the next person that is to be called upon will have a high blood pressure is calculated by dividing the number of persons who had high blood pressure by the total number of the persons.

P = 314 / 1308

Simplifying the known values,

P = 0.240

Therefore, the answer to this item is the third choice.
