2 (9 points) The discrete integer-valued random variable x has the probability mass function (PMF) Px(x) = P(X = x) = cxfor 3 € {1,2,3} and 0 otherwise. 1) (3 points) Find the value of the constant c. 2) (2 points) Find the expectation of X, namely, E(X). 3) (4 points) Find the variance var(X) and the standard deviation ox.
