Question

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. round to three decimal places as needed
a. 0.373
b. 0.241
c. 0.322
d. 0.29

Explanation:

Step1: Calculate empirical probability

The empirical probability is the ratio of people with high blood pressure to total people.
$\text{Probability} = \frac{397}{1232}$

Step2: Compute and round to 3 decimals

Calculate the division and round the result.
$\frac{397}{1232} \approx 0.322$

Answer:

C. 0.322
