# the payout on matching a color (red/black) in a roulette is

the payout on matching a color (red/black) in a roulette is one to one in other words, if you bet a dollar and win, you get a dollar. There are 38 slots on a roulette wheel, 18 of which are red, 18 of which are black and 2 of which are green (0 and 00)1. Compute the expected value for a \$1 bet on  the color red: P(red)= 18/38 = 9/19EV= (9/19) (\$1)=\$0.472. Interpret your answer for part a in the context of the problem: you have a 9 in 19 chance of winning a dollar____________________________________________________________________REFER TO THE PROBLEM ABOVE (I already solved the problem above): The expected value for a \$1 bet is actually the same for any possible bet that can be made in a game of roulette. Use the expected value from part a to compute the payout of winning a game of roulette by placing a bet on any single number.   (fill in the question marks)Winning bet:Color(red/black): Probability= 18/38    Payout=  1 to 1      Expected value?Single number     Probability?                Payout?                         Expected value?
