Question
For a large population of people, the probability distribution for the random variable \( X \) (the number of meals a person ate yesterday) and the assigned probabilities is given below:

| Meals, \( X \)    | 1   | 2   | 3   | 4   | 5   |
|-------------------|-----|-----|-----|-----|-----|
| Probability       | 0.17| 0.35| 0.24| 0.17| ?   |

### Questions

(a) Find \( P(X = 5) \), the probability that a randomly selected person ate 5 meals yesterday.  
\[ P(X = 5) = \_\_\_\_ \]

(b) Find \( P(X \leq 2) \), the probability that a randomly selected person ate 2 or fewer meals yesterday.  
\[ P(X \leq 2) = \_\_\_\_ \]

(c) Find the probability that a randomly selected person ate 1 meal or ate 5 meals yesterday.  
\[ P = \_\_\_\_ \]

(d) Find \( P(X > 1) \), the probability that a randomly selected person ate more than 1 meal yesterday.  
\[ P(X > 1) = \_\_\_\_ \]
