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.

○ 0.172

○ 0.223

○ 0.091

○ 0.14

Explanation:

Step1: Recall probability formula

Probability \( P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \). Here, number of favorable outcomes (people with high - blood pressure) \( n = 340 \), total number of outcomes (total people) \( N=1982 \).

Step2: Calculate the probability

\( P=\frac{340}{1982}\approx0.172 \) (using a calculator to perform the division \( 340\div1982\)).

Answer:

0.172
