4.) According to a recent study, 35% of drivers admitted to tailgating someone before passing them, thinking they can make the car in front of them go faster. Suppose you are on a highway and 5 cars pass you. (a). What is the expected number (average) of vehicles out of five that will tailgate you? What is the standard deviation of the distribution? (b) (c) If t represents the number of cars that will tailgate you before passing, calculate the probability that a car will tailgate you before passing, P(t), for t=0 to t = 5. Use 3 significant figures. P(0)=_ P(1)=_ P(2)= P(3)= P(4)= P(5)= (c) Make a probability distribution for the data in part c. 0.35 PU 03 025 02 0.15 0.1 0.05 0 2 teno, of tailgating cars
