Statistics has always been my weakest point in math, so please bear with me. I'm not asking how to win, just analyzing the game.
Assuming an American Roulette with two zero slots, the greens, or labeled G here:
P(R) = P(B) = 18/38 = 0.4737 P(G) = 2/38 = 0.0526
I'm trying to calculate the probability of a certain sequence to happen, for example: RRRBRG.
Say, n is the length of the sequence (the number of spins), how do I calculate the probability of any given sequence. RRRRRR, or probably GGGGGG? Red and Black have higher probability than green, obviously the P(RRRRRR) is > P(GGGGGG), but how do I calculate this?
