Wheel of Chance

In this game of chance, we have a wheel divided into 8 equal sectors or pie slices. 4 of them are marked $200, 3 are $500 and 1 is $1000.

It costs you $100 to place a bet on any one of the unique numbers on the wheel, and spin once. If the wheel stops with the arrow pointing at the number you chose, you win that amount plus your $100 back, otherwise you lose your bet.
