Help please!!

A roulette wheel has 38 numbered slots, 1 to 36, 0, and 00. The odd numbered slots from 1 to 36 are red and the even numbered slots are black. Both 0 and 00 are green slots. a. SIMULATION: You can easily simulate the roulette game on your TI-83/84/89 by entering RandInt(1,38) and letting 37 = 0 and 38 = 00. Have one partner operate the calculator, and let the other person guess red or black prior to each spin. Perform 20 simulations, then switch jobs. Record your results in the table below. Name Wins Losses b. Suppose you bet $1 to play a game. If you guess red or black and are correct, you win $1 and get your original dollar back. If you're wrong, you lose the $1 bet. Let X= the amount gained on a single play. Complete the probability distribution for X. -1 1 P c. Find the expected amount gained per play. d. Calculate the standard deviation of the amount gained per play. e. Suppose you play two games. Find the total expected amount gained after two plays and the standard deviation of the total amount gained after two plays. A roulette wheel has 38 numbered slots, 1 to 36, 0, and 00.
