![### Problem Summary for Educational Purposes
**Context:**
The provided table and accompanying information summarize the distribution of eighth-grade students at Keisel Middle School based on their handedness (left-handed or right-handed) and gender.
**Table Data:**
| Gender | Left-handed | Right-handed |
|--------|-------------|--------------|
| Female | - | - |
| Male | - | - |
| **Total** | **18** | **122** |
**Problem Details:**
1. **Given Information:**
- There are 5 times as many right-handed female students as there are left-handed female students.
- There are 9 times as many right-handed male students as there are left-handed male students.
- The total number of left-handed students is 18.
- The total number of right-handed students is 122.
2. **Objective:**
Determine which given probability is closest to the probability that a randomly selected right-handed student is female.
3. **Assumptions:**
- None of the eighth-grade students are both right-handed and left-handed.
**Options for Probability Calculation:**
A) 0.410
B) 0.357
C) 0.333
D) 0.250
### Explanation of Probabilities:
To solve for the probability, we can follow these steps:
1. **Let F_l represent left-handed females, M_l represent left-handed males, F_r represent right-handed females, and M_r represent right-handed males.**
2. **Initial Information Setup:**
- F_l + M_l = 18 (total left-handed students)
- F_r + M_r = 122 (total right-handed students)
3. **Using Ratios:**
- F_r = 5 * F_l (since right-handed females are 5 times the number of left-handed females)
- M_r = 9 * M_l (since right-handed males are 9 times the number of left-handed males)
4. **Total Students:**
- Total left-handed students: F_l + M_l = 18
- Total right-handed students: (5 * F_l) + (9 * M_l) = 122
5. **Probability Calculation:**
- First solve the equations to find the actual numbers of left-handed and right-handed students for each gender.
- Then calculate the](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdff7b543-7c53-4567-b2e2-82ba64a4a215%2F25c04c5f-ceaf-450b-8c61-2671c6e7120e%2Fr4zo9jb_processed.jpeg&w=3840&q=75)
