## [Payout tables and the difference between odds and payouts](https://velagamingprime.com/archives/2007/04/payout_tables_and_odds.html)

Two numbers sit beside every wager on a table layout, and they are not the same number. One describes how often an outcome arrives. The other describes what is handed back when it does. The gap between them is the whole arrangement in miniature.

## [What the house edge actually measures](https://velagamingprime.com/archives/2007/02/the_house_edge.html)

The house edge is quoted constantly and defined rarely. It is a single per-unit average, and knowing exactly what it averages over is what makes it useful.

## [The gambler's fallacy and independent trials](https://velagamingprime.com/archives/2006/12/gamblers_fallacy.html)

A sequence of independent trials has no memory. The persistent belief that it does is old enough, and stubborn enough, to have earned a name of its own.

## [Two dice, thirty-six outcomes](https://velagamingprime.com/archives/2006/10/two_dice.html)

Almost everything worth saying about dice follows from one small grid. Drawing it once by hand is worth more than reading a dozen tables of probabilities.
