Question
### Understanding Probability in Basketball Free Throws

#### Scenario

When practicing basketball, Rachel has a 67% chance of making a free throw. She shoots 12 free throws. Let the random variable \( X \) be the number of free throws she makes.

#### Problem 1: Probability Calculation

**Question:**  
Find the probability she makes exactly 5 free throws. Give your answer to at least three nonzero decimal places.

**Input Box:**  
```plaintext
[                                    ]
```

#### Problem 2: Expected Value Calculation

**Question:**  
What is the expected value of \( X \)? Interpret this value.

**Input Box:**  
```plaintext
[                                    ]
```

### Explanation

In this problem, we are dealing with a binomial distribution scenario where the probability of each free throw is constant (67%) and each trial (free throw) is independent of the others. We will calculate the probability for Rachel making exactly 5 free throws out of 12 attempts, and then compute the expected number of successful free throws.
