draw graph very clearly

2. Let X be a discrete random variable with domain {2, 3, 5}, and distribution p(X), given by: p(x) = x/ 10 a) [5 points] Graphically represent the cumulative density function of X. b) [5 points] Compute E[X], the expected value of X. c) [5 points] Compute V[X], the variance of X
