A casino card game takes $10 bets.
Players have a 33% chance of winning $20, and they have a 67% chance of losing their bets.
What is the house edge?
-------------------------------
House random number gains: 10, -10
Corresponding Probabilities: 0.67 , 0.33
-------------------------------
E(gain for the house) = 0.67*10 + 0.33*-10
= 6.7 -3.3
= $3.40
