Can someone please help me figure out the probability portion of this question?

**Reworking Problem 5 - Section 4.2**

**Context:**
Consider the problem of selecting two students randomly from a committee comprising six members—four males and two females. The task is to determine the number of males selected, defined as the random variable \( X \).

**1. Number of Possible Values for \( X \):**

- The random variable \( X \) can take on three different values, which are the number of males that could be selected in the two-student sample.

**2. Values of \( X \) and Their Probabilities:**

Below is the probability density function table that outlines each possible value of \( X \) and the corresponding probability.

| **Value of \( X \)** | **Probability** |
|--------------------|-----------------|
| 0                  | 0               |
| 1                  | \(\frac{12}{21}\) |
| 2                  | \(\frac{3}{21}\)  |

**Notes:**

- The table lists the values of \( X \) in ascending order.
- It's crucial to understand that the probability of \( X = 0 \) is zero, meaning it's impossible to select two females since there are only two females in the group, and we're selecting two students.
- The majority probability occurs when one male and one female are selected, corresponding to \( X = 1 \).
- The calculations involved in understanding these probabilities require combinatorial reasoning, such as determining the number of ways to choose males and females from the committee.

This setup helps students grasp basic probability concepts and apply them to scenarios involving sample selections from small groups.
