A roulette wheel has 38 numbers, 1 through 36, 0, and 00. One-half of the numbers from 1 through 36 are red, and the other half are black; 0 and 00 are green. A ball is rolled, and it falls into one of the 38 slots, giving a number and a color. The payoffs (winnings) for a $1 bet are as follows:?

Red or black                $1                    0                                  $35

Odd or even                $1                    00                                $35

1–18                            $1                    Any single number      $35

9–36                            $1                    0 or 00                         $17

If a person bets $1, find the expected value for each.
