Question

### 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
