9) Let the random variable \( x \) represent the number of tails in five flips of a coin. Construct a table describing the probability distribution, then find the mean and standard deviation.

**Table: Probability Distribution**

| \( x \) | \( P(x) \) | \( x \cdot P(x) \) | \( x^2 \) | \( x^2 \cdot P(x) \) |
|---------|------------|--------------------|-----------|-----------------------|
| 0       |            |                    |           |                       |
| 1       |            |                    |           |                       |
| 2       |            |                    |           |                       |
| 3       |            |                    |           |                       |
| 4       |            |                    |           |                       |
| 5       |            |                    |           |                       |

**Instructions:**

- Complete the table by calculating the probabilities \( P(x) \) for each value of \( x \) using the binomial distribution formula.
- Calculate \( x \cdot P(x) \) and \( x^2 \cdot P(x) \) for each \( x \) value.
- Use the completed table to find the mean (\( \mu \)) and standard deviation (\( \sigma \)) of the distribution.
