Need to show work 11. Building contractors are required by a county planning department to submit two, three, four, five, or six forms, depending on the nature of the project, when applying for a building permit. Let Y -number of forms required of the next applicant. The probability that y forms are required is known to be proportional to y. Thus, P(Y y) ky for y 2,3,4,5, 6 and k > 0. (a) Find the value of k so that...
