Topic: Discrete Random Variables. Let's define a new random variable X in the following way: if the event A occurs X - 0 if the event A does not occur 1. [3 pts] What is the expected value of X? Calculate E[X]. 2. [3 pts] What is the variance of X? Calculate Var(X). 3. [4 pts] Let P( A) represent the probability of the event A. Calculate P(X > 0), P(X
