expect from this stock? 26. CAR SALES Ken King, the owner of King's Kars, determines that the number of daily new car sales may be measured by the discrete random variable X with this probability distribution: P(X = 0) = 0.05, P(X = 1) = 0.15, P(X = 2) = 0.20, P(X = 3) = 0.25, P(X = 4) = 0.12, P(X = 5) = 0.13, P(X = 6) = 0.05, P(X = 7) = 0.02, P(X = 8) = 0.03 a. Describe the event (X = x). b. Draw the histogram for this random variable. c. How many new cars should Ken expect to sell on a randomly selected day? d. Find the variance and standard deviation of Ken's daily new car sales
