----
Your expected winnings are 5.25. But you
paid 6 to play the game. So your expected
"winnings" are really -0.75. You can expect
to lose 75 cents each time you play the game.
==============================================
To make the game "fair", the vendor should only
charge $5.25 to play the game.
