Question

estimate the probability of the event. 8) 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. a) 0.322 b) 0.29 c) 0.373 d) 0.241

Explanation:

Step1: Recall Probability Formula

The probability of an event is the number of favorable outcomes divided by the total number of outcomes. Here, favorable outcomes (people with high blood pressure) is 397, total outcomes (total people) is 1232. So the formula is $P = \frac{\text{Number of people with high BP}}{\text{Total number of people}}$.

Step2: Calculate the Probability

Substitute the values into the formula: $P=\frac{397}{1232}$. Calculate this division: $397\div1232\approx0.322$.

Answer:

A) 0.322
