WebWe decide to analise the Roulette game with a Binomial distribution. In the game there are 37 numbers, from 1 to 36 plus 0, we analise the probability of winnig or losing for 1 single shot, and they are 1/37 (winning) and (36/37) losing. Studying 35 shots we can now derive a Binomial distribution where X->Bin (35,36/37). the problem is that the ...
