People pay 10cents and can win prizes. One slot is 100 cents worth, 3 slots are worth 30 cents and 6 slots are worth 10 cents. All other 40 slots are worth nothing. My question is, would this roulette be profit for me or for a player? Cause I am not sure how to calculate them correctly in this case. Thank you.
