✒️So the variance of X is the weighted average of the squared deviations from the mean μ, where the weights are given by the probability function pX(x) of X.

hope it helps.

Answer:

So the variance of X is the weighted average of the squared deviations from the mean μ, where the weights are given by the probability function pX(x) of X. The standard deviation of X is defined to be the square root of the variance of X. That is, sd(X)=σX=√var(X).
