Verify that the following function is probability mass functions, and determine the requested probabilities. f(x) = (8/7)(1/2)x, x = 1, 2, 3 P(X 1) = P(X > 1) = P(2 < X < 6) = P(X 1 or X > 1) = P(X 1 X > 1) = Determine the cumulative distribution function. State P(1 < X 2) in terms of the cumulative distribution function and then determine the probability
