Question

Suppose we have a bag with 8 slips of paper in it. Six of these have a 1 on them and the other two have a 3 on them.

What is the expected value of the number shown when we draw a single slip of paper?

Answer 1

easy way to do it is this
pick all 8
you get a total of \(6+2\times 3=12\)

Answer 2

12?

Answer 3

averaged over the 8 picks, the expected value is \(\frac{12}{8}=\frac{3}{2}\)
