Question 763966: If he selects 3 bills at a time what is the probability of selecting a group that has an average value of equal to or less than $25? Answer by solver91311(24713) (Show Source):
Depends on the composition of the group of bills from which the three are selected. For example: Draw three bills from a pile of twentys and fiftys. The probablity of a sum equal to $25 is zero. You need to know the number of ways that you can pull exactly 2 tens and 1 five from your pile.
