When playing Americanroulette, the croupier(attendant) spins a marble that lands in one of the 38 slots in a revolving turntable. The slots are numbered 1 to36, with two additional slots labeled 0 and 00 that are painted green. Consider the numbers 0 and 00 as neither even nor odd. Half the remaining slots are colored red and half are black.
