Transcribed Image Text:**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.
