An automatic camera records the number of cars running a red light at a traffic light. Data shows, on average 20% of light changes record a car running a red light. Assume that the data has a binomial distribution. Create a probability distribution for a car running a red light in 3 light changes.
Homework Answers
X = random variable indicating the car running a red light in 3 light changes
n = 3

2. Consider the following problem associated with synchronizing traffic lights. A particular traffic light (Light A) has a cycle as follows: Red = 1 min Green = 1.5 min Yellow = 0.5 min Some distance before Light A is another light (Light B). Due to varying drivers and conditions, the travel time between the two lights varies from vehicle to vehicle. Data suggest that 40% of all cars leaving Light B at a time when Light A is red are...

To combat red light running crashes many states have installed red light cameras at dangerous intersections to photograph the license plates of vehicles that run the red light. How effective are photo-red enforcement programs in reducing red-light-running crash incidents at intersections? A state's department of transportation conducted a comprehensive study of its photo-red enforcement program. In one portion of the study, the department provided crash data both before and after installation of red light cameras at several intersections. The data...

A traffic light on campus remains red for 15 seconds at a time. A car arrives at that light and finds it red. Assume thet the waiting time t seconds at the light follows a uniform density function f (a) Calculate the car's chances of waiting at least 5 seconds at the red light. (Round your answer to one decimal place.) (b) Calculate the probability of waiting no more than 10 seconds at the red light. (Round your answer to...

In a preliminary study to determine whether the installation of a camera designed to catch cars that go through red lights affects the number of violators, the number of red-light runners was recorded for each day of the week before and after the camera was installed. These data are listed here. Can we infer that the camera reduces the number of red-light runners? Day Sunday Monday Tuesday Wednesday Thursday Friday Saturday Before 1 7 21 27 18 20 24 16...

A car wash has one automatic car wash machine. Cars arrive according to a Poisson process at an average rate of 5 every 30 minutes. The car wash machine can serve customers according to a Poisson distribution with a mean of 0.25 cars per minute. What is the probability that there is no car waiting to be served?

Suppose that in a certain shop, there is a little (sort of) traffic light in the counter. When finishing their purchase, the buyer has to activate a button which makes the light go either green or red. If the light goes green, the client gets their purchase for free. The light is programmed to go green with a probability of 0.015. a) Calculate the probability that the fiftieth customer who activates the button will be the first to take their...

The number of surface flaws in a plastic roll used in interior of cars has a poisson distribution with a mean of 0.07 flaws per square foot of plastic roll. Assume a car interior contains 9 square feet of plastic roll. If 10 cars are sold to a rental company, what is the probability that at most one car has a surface flaw? If 10 cars are sold to the rental company, what is the expected number of cars with...
