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.
