Question
A contractor is required by a county planning department to submit one, two, three, four, five, or six 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, ..., 6. (Enter your answers as fractions.) (a) What is the value of k? [Hint: p(Y) Σ y = 1 k= (d) Could p(y) (b) What is the probability that at most three forms are required? = 6 (c) What is the probability that between two and four forms (inclusive) are required? 87 = 1] ---Select--- for y = 1, ..., 6 be the pmf of Y? 6 · because Σ p(y) = y = 1
