In American roulette, the payout for winning on green is $17. This means that if you bet $1 and it lands on green, you get $17 as a prize.In the previous exercise, you created a model to predict your winnings from betting on green.

Now, compute the expected value of \(X\), the random variable you generated previously.

Instructions
