question

A typical roulette wheel used in a casino has 38 slots that are numbered 1,2,3,…,36,0,001,2,3, \ldots, 36,0,00, respectively. The 0 and 00 slots are colored green. Half of the remaining slots are red and half are black. Also, half of the integers between 1 and 36 inclusive are odd, half are even, and 0 and 00 are defined to be neither odd nor even. A ball is rolled around the wheel and ends up in one of the slots; we assume that each slot has equal probability of 1/381 / 38, and we are interested in the number of the slot into which the ball falls. Let A={0,00}A=\{0,00\}. Give the value of P(A)P(A).
