What is the expected value of playing an American Roulette (choose the closest value)?   A few notes: a bet is $1. There are 38 numbers in the Roulette (00,0,1-36), and the casino pays 1 to 35. You can bet in one number, and if that number comes out, you get 35. If it falls in any other number, you lose the dollar that you bet.
