Consider the following pmf: p(x) = k for x = 0, 1, 2, 3, 4, 5, 6, 7, 8 Determine the value of k. Enter your answer to four decimal places using conventional rounding methods.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
