1. The Jackpot on this machine is 3 Jackasses. What is the probability of a Jackpot?

2. Assume the Jackpot is $1000, and it is the only payoff.
If it costs you $1 each time you play, how much would you expect to lose before you win the Jackpot?

3. Your expected gain each time you play is the product of your chance of winning and how much you may win. Likewise, your expected loss each time you play is the product of your chance of losing and how much you may lose. Your expected net profit, therefore, is the difference between your expected gain and your expected loss. What is your expected net profit?

4. What is the chance of exactly 2 Armadillos in any position.
Hint: Think AAX + AXA + XAA, and don�t count any combination twice.

5. What is the probability of 1 Chimp, 1 Elephant, and 1 Jackass in any order?
