Question

   Let a chip be taken at random from a bowlthat 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=5if the outcome is a red chip, and let X = 10 if the outcome is ablue chip. a)Find the p.m.f of X. b)Graph the p.m.f as a bar graph.    Let a chip be taken at random from a bowlthat 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=5if the outcome is a red chip, and let X = 10 if the outcome is ablue chip. a)Find the p.m.f of X. b)Graph the p.m.f as a bar graph.

Explanation / Answer

p(R)= 3/10=.3 p(B)= 1/10 = .1
X(1)= .6 X(5)= .3 X(10)= .1
