Answer :
To find the probability that a randomly chosen male dormitory resident had a flu shot, we need to focus only on the group of male residents.
Here's how you can calculate it step-by-step:
1. Identify Relevant Data:
- The total number of male residents is 51.
- Out of these 51 male residents, 39 had received a flu shot.
2. Set Up the Probability Formula:
- The probability you're looking for is the chance that a resident had a flu shot given that he is male. This is calculated by dividing the number of males who had a flu shot by the total number of males.
3. Calculate the Probability:
- Probability = (Number of males who had a flu shot) / (Total number of male residents)
- Probability = 39 / 51
4. Simplify the Fraction:
- Divide 39 by 51 to get the probability as a decimal.
Calculating this gives us approximately 0.7647, which is the probability that a randomly chosen male resident had a flu shot. Therefore, if you were to select a male resident at random, there is a 76.47% chance that he had a flu shot.
