"Time headway" in traffic flow is the elapsed time between the time that one car finishes passing a fixed point and the instant that the next car begins to pass that point. Let X = the time headway for two randomly chosen consecutive cars on a freeway during a period of heavy flow (sec). Suppose that in a particular traffic environment, the distribution of time headway has the following form. k. X > 1 f(x) = 6 10 X51 (a)...

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...

I need help on Part D, please!!
The probability is 0.45 that a traffic fatality involves an intoxicated or alcohol-impaired driver or nonoccupant. In ten traffic fatalities, find the probability that the number, Y, which involve an intoxicated or alcohol-impaired driver or nonoccupant is a. exactly three; at least three; at most three. b. between two and four, inclusive. c. Find and interpret the mean of the random variable Y d. Obtain the standard deviation of Y a. The probability...

A major traffic problem in the Greater Cincinnati area involves traffic attempting to cross the Ohio River from Cincinnati to Kentucky using Interstate 75. Let us assume that the probablity of no traffic delay in one perio given no traffic delay in the preceding period, is 0.9 and that the probability of finding a traffic delay in one period, given a delay in the preceding period, is 0.65. Trafie is classified as having ether a delay or a no-delay state,...

A particularly long traffic light on your morning commute is green 40% of the time that you approach it. Assume that each morning represents an independent trial. Let denote the number of mornings the light is green. a) Over 10 mornings, what is the probability that the light is green on exactly 4 days? Round your answer to three decimal places (e.g. 98.765) b) Over 20 mornings, what is the probability that the light is green on exactly 8 days?...
