Question

Transcribed Image Text:**Instructions:**
1. Draw a Venn diagram and label the data.
a. What is the probability that a person selected at random from the survey group is male?
b. What is the probability that a person selected randomly from the survey group is a male wearing jewelry?
**Explanation:**
A Venn diagram is a visual representation used to show relationships between different groups. It typically consists of overlapping circles, each representing a set. In this context, you can use one circle to represent males and another to represent people wearing jewelry. The area where the circles overlap will represent males wearing jewelry.
To solve the probabilities:
- **For (a):** Calculate the probability by dividing the number of males by the total number of people in the survey group.
- **For (b):** Calculate the probability by dividing the number of males wearing jewelry by the total number of people in the survey group.
