Assume you have applied to two different jobs A and B. In the past, 20 % of applicants who applied for Job A were offered jobs, while Job B offered 10 % of the applicants. Assume events are independent of each other.

An investment banker estimates the following probability distribution for the earnings per share (EPS) of a firm.
x(EPS) 2.25 2.50 2.75 3.00 3.25 3.50 3.75
P(x) 0 .05 0.10 0.20 0.25 0.20 0.15 0.05
Calculate mean (i.e., the expected value) and standard deviation of the EPS.
