I believe what Ballmer wanted to hear are clarifying questions.
Eg. Can I stop at any time? If yes, I will stop before I go into the negative. If I cannot stop but must continue the game until I guessed the right number, I will most likely lose money. Then go into a simple computation of XY terms where X is the probability and Y is the payout or loss for maybe a dozen terms.
