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?...

Reserve Problems Chapter 10 Section 1 Problem 3 The time delay
is measured for a city street. Variability in this value is
estimated as (for time in minutes) by experience. Traffic signs and
lights were recently altered to facilitate traffic and reduce
delays. Delay times in minutes for a random car sample before and
after the rearrangement are shown below. Before 7.2 7.1 7.1 7.0 7.4

"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)...
