Question
The following table shows the probability of a cellular phone company selling a certain number of credit card contracts. The problem asks: What is the standard deviation for this probability distribution? Also, what is the probability that they sell 6 or more contracts in a row?

**Table: Number of Credit Cards**

| x  | P(x) |
|----|------|
| 4  | 0.40 |
| 5  | 0.30 |
| 6  | 0.10 |
| 8  | 0.15 |
| 10 | 0.05 |

- **x** represents the number of contracts sold.
- **P(x)** represents the probability of selling **x** contracts.

The task is to calculate the standard deviation of this probability distribution and determine the probability that 6 or more contracts are sold consecutively.
