Question

A spinner marked off in four equal-sized regions, numbered 1, 2, 3, and 4, 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(3), and explain what this number represents.
e) Find µ, and explain what this number represents.
a) What is the range of X?

OB. (1,2,3)
O C. (0, 1, 2, 3)
OD. (0, 1, 2, 3, 4, 5)
