### Probability Exercise: Analyzing Student Grades by Gender

**Scenario:**
A group of students took a test, and their grades along with their gender are summarized in the table below.

#### Summary Table:

| Grade | A | B | C | Total |
|-------|---|---|---|-------|
| **Male** | 9 | 6 | 7 | 22 |
| **Female** | 19 | 13 | 14 | 46 |
| **Total** | 28 | 19 | 21 | 68 |

#### Questions:

1. **Find the probability that the student got a B:**
    \[ \text{Probability} = \frac{\text{Number of students with a B}}{\text{Total number of students}} \]
    
    \[ \text{Probability} = \frac{19}{68} \]

2. **Find the probability that the student was male AND got a "C":**
    \[ \text{Probability} = \frac{\text{Number of males with a C}}{\text{Total number of students}} \]
    
    \[ \text{Probability} = \frac{7}{68} \]

3. **Find the probability that the student was female OR got a "C":**
    \[ \text{Probability(Female)} + \text{Probability(C)} - \text{Probability(Female and C)} \]

    - Probability (Female):
        \[ \text{Probability} = \frac{46}{68} \]
    - Probability (C):
        \[ \text{Probability} = \frac{21}{68} \]
    - Probability (Female and C):
        \[ \text{Probability} = \frac{14}{68} \]

    \[ \text{Total Probability} = \frac{46}{68} + \frac{21}{68} - \frac{14}{68} = \frac{53}{68} \]

4. **Find the probability that the student was male GIVEN that the student got an 'A':**
    \[ \text{Probability} = \frac{\text{Number of males with an A}}{\text{Total number of students with an A}} \]

    \[ \text{Probability} = \frac{9}{28} \]
