1. Compute the expected value for a $1 bet on the color red

2. Interpret your answer for part a in the context of the problem

______________________________________________________-

REFER TO THE SETUP OF THE PROBLEM ABOVE: The expected value for $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 table and answer the question marks
