c) Find the edf of X. 2. A contractor is required by a county planning department to submit one, two, three, four, and five 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}. The probability that y forms are required is known to be proportional to y-that is, p(y) = ky for y= 1,2,3,4,5. a) What is the value of k? (Hint: Σp(y) = 1.) y=l b) What is the probability that at most three forms are required?
