Question
![**Problem Statement:**
Find the indicated probability.
In a certain class of students, there are:
- 8 boys from Wilmette
- 4 girls from Kenilworth
- 4 girls from Wilmette
- 2 boys from Glencoe
- 5 boys from Kenilworth
- 2 girls from Glencoe
If the teacher calls upon a student to answer a question, what is the probability that the student will be from Kenilworth?
**Answer Choices:**
- ○ 0.16
- ○ 0.36
- ○ 0.2
- ● 1
The correct answer is **0.36**.
**Explanation:**
To find the probability that the student is from Kenilworth:
1. Count the total number of students from Kenilworth:
- 4 girls from Kenilworth
- 5 boys from Kenilworth
- Total from Kenilworth = 4 + 5 = 9
2. Calculate the total number of students:
- 8 boys from Wilmette
- 4 girls from Wilmette
- 2 boys from Glencoe
- 2 girls from Glencoe
- Total = 8 + 4 + 2 + 2 + 9 (Kenilworth) = 25
3. Probability that a student is from Kenilworth:
\[
\text{Probability} = \frac{\text{Number of Kenilworth students}}{\text{Total number of students}} = \frac{9}{25} = 0.36
