Question

A contractor is required by a county planning department to submit one, two, three, or four forms (depending on the nature of the project) in applying for a building permit. Let $Y$ = the number of forms required of the next applicant. Suppose that Y has pmf $P(Y = y) = \frac{y}{10}$, for $y = 1, 2, 3, 4$ 1. Find $P(Y > 2)$. 2. Find $E(\frac{1}{Y})$.
