**MathMate**, Monday, August 17, 2009 at 11:28amFor a balanced die, the probability of getting an even number is n({2,4,6})/n({1,2,3,4,5,6})=1/2.

Similarly, the probability of getting an odd number is 1/2.

Thus, the expected gain/roll is

expected gain - expected loss

= 0.5*$22 - 0.5*$12

= $11-$6

=$5 per roll on average in the long run
