What is Mean and Variance in Probability Distributions about?

The document is a lesson module on solving problems involving mean and variance of probability distributions. It begins with recalling the formulas for mean, variance, and standard deviation of discrete random variables. It then provides two examples of calculating the mean of probability distributions involving rolling a die and expected gain from tossing coins. Finally, it presents two examples of finding variance - one involving number of pizzas sold daily and another involving number of monthly absences
