You and your friends are going to Vegas. They find a roulette table and while watching your friends play, you ponder if this is mathematically a good decision in the long run. You choose to bet \$1 while you think.

There are 38 spaces on the wheel and you bet on one number of out of the 38 being chosen. If you choose correctly you will receive \$35, if not then you lose your bet. You are good at math and quickly calculate that your average return for this \$1 bet is -\$0.0526 so you decide not to play anymore.

While asleep you are dreaming about a wonderful fantasy roulette where you average \$0.44 on every \$1 bet. Assuming you still get \$35 for choosing the correct number and lose \$1 when not choosing the correct number, how many spaces does this fantasy roulette wheel contain?
