3. A contractor is required by a country planning department to submit one, two, three, four, or five forms 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, ... , 5. a) What is the value of k? b) What is the probability that between two and four forms (inclusive) are required? c) Could p(y) = y2/50 for y = 1, 2, ..., 5 be the pmf of Y? %3D
