Question
**Educational Resource: Probability and Statistics**

**Overview:**

This is an analysis of a group's test results, divided by grades (A, B, C) and gender (male, female). The table summarizes the results:

|       | A | B  | C  | Total |
|-------|---|----|----|-------|
| Male  | 2 | 15 | 19 | 36    |
| Female| 3 | 9  | 14 | 26    |
| Total | 5 | 24 | 33 | 62    |

**Probability Questions:**

1. **Find the probability that the student received a C in the class.**
   - Calculation: \(\frac{\text{Total C}}{\text{Total Students}}\)

2. **Find the probability that the student is a male.**
   - Calculation: \(\frac{\text{Total Males}}{\text{Total Students}}\)

3. **Find the probability that the student was a male and received a C in the class.**
   - Calculation: \(\frac{\text{Male C}}{\text{Total Students}}\)

4. **Find the probability that the student received an A in the class, given they are female.**
   - Calculation: \(\frac{\text{Female A}}{\text{Total Females}}\)

5. **Find the probability that the student is a female given they received an A in the class.**
   - Calculation: \(\frac{\text{Female A}}{\text{Total A}}\)

6. **Find the probability that the student is a female and received an A in the class.**
   - Calculation: \(\frac{\text{Female A}}{\text{Total Students}}\)

7. **Find the probability that the student received an A given they are male.**
   - Calculation: \(\frac{\text{Male A}}{\text{Total Males}}\)

8. **Find the probability that the student received an A and they are male.**
   - Calculation: \(\frac{\text{Male A}}{\text{Total Students}}\)

Use this data to further understand the relationship between gender and performance in this group of students by calculating the requested probabilities.
