Check in each case whether the given function can serve as the probability distribution of an appropriate random variable. (a) f(x) = (2 x)/4 for x = 0, 1, 2; (b) f(x) = x - 2/9 for x = 1, 2, 3, 4, 5, 6; (c) f(x) = x^2 - 6x + 9/10 for x = 1, 2, 3, 4, 5; (d) f(x) = x^2 - 6x + 8/5 for x = 1, 2, 3, 4, 5.

Determine whether or not the distribution is a discrete probability distribution and select the reason why or why not. x −4 −3 −2 P(X=x) 0.55 0.39 0.06 Answer First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision. Decide Yes No Reason Since the probabilities lie inclusively between 0 and 1 and the sum of the probabilities is equal to 1. Since at least one of the probability values is greater than...
