A contractor is required by a county planning department to submit one, two, three, four, or 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 be proportional to y-that is, p(y) = ky for y = 1, .... 5. (Enter your answers as fractions.) (a) What is the value of k? (Hint: P(Y) = 1) y-1 k = (No Response) (b) What is the probability that at most three forms are required? (No Response) (c) What is the probability that between two and four forms (inclusive) are required?
