**January 2015 PUZZLE - "Even Money Powerball Bet?"**

*Submitted by Gene Aronson*

To win the Powerball jackpot one must choose five different numbers from 1 to 59, plus the Powerball number from one of 35 numbers. The bet is two dollars. One can win in nine ways: the largest prize is for matching all 5 numbers and the Powerball, and is a variable amount. The other 8 amounts are fixed payouts. Here are all nine ways to win, and their prize amounts:

- 5 numbers + Powerball (PB): JACKPOT
- 5 numbers:$1,000,000
- 4 numbers +PB:$10,000
- 4 numbers:$100
- 3 numbers +PB:$100
- 3 numbers:$7
- 2 numbers +PB:$7
- 1 number +PB:$4
- PB only: 4$

**The February Bonus:**What is the jackpot amount for an even bet (expected winnings = zero), for the situation in which (A) only the jackpot is considered, and the situation in which (B) all nine prizes are considered?
