An automobile service facility specializing in engine tune-ups knows that50% of all tune-ups are done on four-cylinder automobiles, 20% on six-cylinder automobiles, and 30% on eight-cylinder automobiles. Let X = thenumber of cylinders on the next car to be tuned. What is the pmf of X?P(x)

Since these probabilities sum to 1 (i.e., 0.50+0.20+0.30=1.00), they form a valid pmf. Probability…
