One throws a fair dice until he gets "1" or "6". What would
be the expectation for the sum of all the numbers you obtained?

10.5

14 if the final throw (1 or 6) is counted.

Are you sure? I thought I counted the final throw.

Actually, you did. (Fortunately the averages of {2,3,4,5} and {1,6} are
the same. 8-))

Let's see, an
average of 3.5 points per throw, an average of 3 throws counting the
final throw.
