You can put this solution on YOUR website! Alexi's wallet contains four $1 bills, three $5 bills, and one $10 bill. IF Alexi randomly removes two bills without replacement, determine the probability that the bills will total $15?
---------------
It has to be a $10 and a $5.
The chance of a $10 is 1 of 8. Then the chance of a $5 is 1 of 7.
8*7 is 56, but it could be the $5, then the $10, so that's another 1 of 56.
Overall, it's 2 of 56, or
1/28.
