Next, friend B did a bet on RED with 900 bucks while I and friend A were observing. He won 1800.

1800 - 900 (bet) = Profit of 900.

900 - 400 (amount we lost before) = 500. We did a profit of 500 bucks in less than 30 minutes. It's easy to make money off Casinos. However 99% of people that go to Casinos, don't use their heads.
