The chance of picking a diamond picture card (sounds like A,K,Q,or J) is 4/52 or 1/13

You win 100(1/13) = 100/13 = $7.69

Since you pay $10 to play, your expected earning are 7.69 - 10 = -2.31

You will expect to have a loss of $2.31 every time you play

2.31 is what you expect to lose every time you play, therefore 10000(2.31) = $23100
