A spinner marked off in eight equal-sized regions, numbered 1, 2, 3, 4, 5, 6, 7, and 8, is spun twice. Let the random variable X be the nonnegative difference between the numbers of the regions where the pointer stops, and define a probability mass function g(x) = P(X =x). a) State the range of X. b) Write g as a set of ordered pairs. c) Draw a probability distribution as a histogram. d) Find g(6), and explain what this number represents. e) Find µ, and explain what this number represents. ..... a) What is the range of X?
