7. The probability that a vehicle will change lanes while making a turn is 60%. Suppose that a random sample of seven vehicles is observed making turns at a busy intersection. a. Use the binomial probability table to show the probability that r = 0, 1, 2, 3, 4, 5, 6, 7 vehicles make a lane change while turning. Complete the table and make a histogram to graph the distribution. P(r) 0 2 4 6
