![A contractor is required by a county planning department to submit one, two, three, four, five, six, or seven 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, ..., 7. (Enter your answers as fractions.)
(a) What is the value of k? [Hint:
P(y) = 1]
k=
(b) What is the probability that at most four forms are required?
(c) What is the probability that between two and six forms (inclusive) are required?
y²
(d) Could p(y) =
