-## Question Text
-
-Recall from Section 3.4, we calculate the expected value of a discrete random variable with the following formula:
-
-$$ E(X) = \sum\_{i=1}^k x_i P(X=x_i)$$
-
-Use this probability rule to derive the mean of a Bernoulli random variable, i.e. a random variable $$X$$ that takes value $$1$$ with probability $$p$$ and value $$0$$ with probability $$1 - p$$. That is, compute the expected value of a generic Bernoulli random variable.
