Let X be a random variable with the following probability distribution.
Value x of X P(X = x)
Find the expectation E(X) and the variance var(x) of X.
1. E(X) =
2. Var(X) =
In the following question, mean and variance are calculated for a probability distribution where the values and their associated probabilities are provided. This solution includes two brief calculations.
