### Probability Distribution and Color Blindness in Males

When conducting research on color blindness in males, a researcher forms random groups with five males in each group. The random variable \( x \) represents the number of males in the group who have a form of color blindness. The task is to determine whether a probability distribution is given. If a probability distribution is present, you can find its mean and standard deviation. Otherwise, identify the requirements that are not satisfied.

The table below shows the values for \( x \) and their corresponding probabilities \( P(x) \):

| \( x \) | \( P(x) \) |
|---------|------------|
| 0       | 0.657      |
| 1       | 0.286      |
| 2       | 0.052      |
| 3       | 0.004      |
| 4       | 0.001      |
| 5       | 0.000      |

#### Question

Does the table show a probability distribution? Select all that apply:

- [ ] A. Yes, the table shows a probability distribution.

- [ ] C. No, the sum of all the probabilities is not equal to 1.
- [ ] D. No, not every probability is between 0 and 1 inclusive.
- [ ] E. No, the random variable \( x \) is categorical instead of numerical.
