Cite a real-life situation that you can use the skills in computing the mean, variance and standard deviation. Construct its probability distribution, then compute the mean, variance and standard deviation. Interpret the result.​

Answer:

How do you interpret the mean and the variance of a discrete random variable?

For a discrete random variable X, the variance of X is obtained as follows: var(X)=∑(x−μ)2pX(x), where the sum is taken over all values of x for which pX(x)>0. 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 :>
