Keno odds, priced: the chance of every hit count from one pick to ten

Forty numbers, ten drawn, up to ten marked. That is the whole of keno’s probability, and it can be computed to the last digit for every ticket you can buy. We priced all fifty-five hit counts from the engine’s draw loop and its forty payout tables: how many hits to expect, how rare a clean sweep is, and what the ×1,000 cell is actually worth.
