question 24 (5 points)
find the indicated probability.
of 1003 people who came into a blood bank to give blood, 288 were ineligible to give
blood. estimate the probability that the next person who comes in to give blood will be
ineligible to give blood.

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 (ineligible people) is 288, total outcomes (total people) is 1003.
$$P(\text{ineligible}) = \frac{\text{Number of ineligible}}{\text{Total number of people}}$$

Step2: Substitute Values

Substitute the given values into the formula:
$$P(\text{ineligible}) = \frac{288}{1003}$$

Step3: Calculate the Result

Divide 288 by 1003:
$$\frac{288}{1003} \approx 0.287$$

Answer:

The probability that the next person will be ineligible to give blood is approximately $\frac{288}{1003} \approx 0.287$ (or in fraction form $\frac{288}{1003}$).
