A) A highway patrol officer is looking for speeders on 880. So far, all 400 cars that have passed her patrol car have been under the speed limit. What are the chances that the next car will be speeding? False. This question is asking about geometric probability since it’s the probability that the first speeder will be the 401st car. Additionally, we don’t know probability and don’t know whether it’s the same for all cars. B) How many ways can 15 students be seated in a row of 4 desks so that there is always at least one empty desk between the students? False. This question is a combination and cannot be calculated with the binomial formula. C) The probability that the commute from Berkeley to San Francisco will take less than 40 minutes during rush hour is .27. If...
