The time between arrivals of vehicles at a particular intersection follows an exponential probability distribution with a mean of 10 seconds.
(a)
Sketch this exponential probability distribution.
A graph with 1 continuous curve is given. The area under the curve is shaded.
  • The horizontal axis is labeled: x and ranges from 0 to 30.
  • The vertical axis is labeled: f(x) and ranges from 0 to 0.15.
  • The curve begins near (0, 0.06) and curves down to the right.
  • It leaves the viewing window near (30, 0.01).
