- Definition
- Example - Let T be the time we have to wait until the next bus comes along. Assume that the next bus arrives at a time which is "equally likely" to be anywhere in the next 10 minutes.
  - What is the p.d.f of T?
  - What is the c.d.f. of T?

We will have a short problem session on Friday and then continue with the material in Chapter 5.
