Option C: np is the expression used for calculating the mean of a binomial distribution.

Explanation:

From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.

Option A: npq

The variance of the binomial distribution can be calculated using the expression npq.

Hence, Option A is not the correct answer.

Option B: $\sqrt{npq}$

The standard deviation of the binomial distribution can be calculated using the expression $\sqrt{npq}$

Hence, Option B is not the correct answer.

Option C: np

The mean of the binomial distribution can be calculated using the expression np

Hence, Option C is the correct answer.

Option D: $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

The mean of the binomial distribution cannot be determined using the expression $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

Hence, Option D is not the correct answer.
