Let a chip be taken at random from a bowl that contains six white chips, three red chips, and one blue chip. Let the random variable X = 1 if the outcome is a white chip, let X = 5 if the outcome is a red chip, and let X = 10 if the outcome is a blue chip.

a) Find the p.m.f. of X.
b) Graph the p.m.f. as a bar graph.
