 Sitting on the Fence (Posted on 2013-08-13)
Ann has a choice of two babysitting payment options:
1. She can accept a flat rate of \$15 for a night's work, or:
2. She can choose two of six sealed envelopes containing \$1, \$1, \$5, \$5, \$10 and a \$20 bill.
(For example, the second option could leave Ann with as little as \$2 or as much as \$30 for a night's work.)

Assuming that Ann will have to babysit for a very long period of time, which is the better payment option for her?

I think this problem is a difficulty 1.  I just took the total of the 6 envelopes and divided by 3 to arrive at \$14, which is not as good as \$15.

If you prefer, make believe that Ann works 3 nights, and gets all of the 6 envelopes over the course of 3 nights.  Then the comparison is between \$42 and \$45.
