Transcribed Image Text:2. We have two fair dice, one red and one blue. When we roll them together, the outcome can
be shown as an order pair, (R, B) where R and B are numbers from the red and the blue die,
respectively. Let X be a random variable defined by X(R, B) = R - B where R and B are
numbers from red and blue dice, respectively.
(a) What is the probability mass function for the random variable? Show that as a table.
