![**Probability Distribution Exercise**
This exercise assumes familiarity with counting arguments and probability (see Probability and Counting Techniques).
**Scenario:**
Kent's Tents has 8 green knapsacks and 4 yellow ones in stock. Curt selects 4 of them at random. Let \( X \) be the number of green knapsacks he selects. Give the probability distribution. (Enter your probabilities as fractions.)
**Table:**
| \( x \) | 0 | 1 | 2 | 3 | 4 |
|-----------------|-------------|---------------|--------------|--------------|-------------|
| \( P(X = x) \) | (input) | (input) | (input) | (input) | (input) |
**Questions:**
- Find \( P(X \leq 2) \). (Enter your probability as a fraction.)
\[ P(X \leq 2) = (input) \]

**Explanation of Diagram:**
The main diagram is a table used to represent the probability distribution of a discrete random variable \( X \), which in this case denotes the number of green knapsacks selected.
- The first row of the table contains possible values that \( X \) can take, ranging from 0 to 4.
- The second row is for the corresponding probabilities, \( P(X = x) \), that Curt will select exactly 0 to 4 green knapsacks out of the 4 that he selects at random.
The table is outlined, with input fields in the corresponding cells where users are expected to enter the probabilities as fractions.
In addition to the table, there's a prompt to find the probability that \( X \) is less than or equal to 2, also to be entered as a fraction.
