A roulette wheel contains 38 numbers ​(18 are​ red, 18 are​ black, and 2 are​ green). When the roulette wheel is​ spun, the ball is equally likely to land on any of the 38 numbers. Suppose that you bet ​$6 on red. If the ball lands on a red ​number, you win ​$6​; otherwise you lose your ​$6. Let X be the amount you win on your ​$6 bet. Then X is the random variable whose probability distribution is as follows.x6minus6​P(Xequals​x)0.4740.526a. Find the expected value of the random variable X.The expected value is nothing.
