How can I do this problem in excel?


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).

  • 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, 0.10) and curves down to the right.

  • It leaves the viewing window near (30, 0).
