What is the expected value of a discrete probability distribution?
The expected value of a discrete probability distribution is the weighted average of all possible outcomes, where the weights are the probabilities of each outcome

What is the formula for calculating the standard deviation of a normal distribution?
The standard deviation of a normal distribution is the square root of the variance.
