We explore the properties of a discrete distribution of a random variable for the number of ice creams sold. This includes finding the expected value, variance and standard deviation for the original distribution, two distributions added together, the distribution times a constant, and the distribution plus a constant.
Note that there is an error at 7:13. It should say Var (aX) = a^2 Var(X). (The constant is squared)
