The probability is 55% that a car will change lanes while making a turn at a busy intersection. Suppose that a random sample of 5 cars is observed making turns at the busy intersection. Find the expected number of cars that will make a lane change while turning at the intersection.

The probability that a vehicle will change lanes while making a turn is 55%. Suppose a random sample of 7 vehicles are observed making turns at a busy intersection. (a) Find the probability that no more than 4 vehicles will change lanes while making the turn.

The probability that any single driver will turn left at an intersection is .2. The left turn lane at this intersection has room for three vehicles. If the left turn lane is empty when the light turns red and five vehicles arrive at this intersection while the light is red, find the probability that the left turn lane will hold the vehicles of all of the drivers who want to turn left.

Express all probabilities as fractions. The United Van Lines moving company has a truck filled for deliveries to five different sites. If the order of the deliveries is randomly selected, what is the probability that it is the shortest route?
