The actual odds of winning a Red or Black wager are 1.05:1, with a probability of occurance of 47.37% because there is the chance the ball could land in the 0 or 00 spot of the wheel.

The only 50/50 odds available in a casino are on the craps table, and they are not readily apparent to the unschooled bettor. The best bets on the table are the pass line
point bets (with odds). These bets can be placed in addition to your come or pass line bets, and offer true odds for payouts, meaning the house has no advantage over the player. Single odds means you may make an additional wager equal to your original bet. Double odds means up to two times your bet and so on up to the seldom offered 100 times odds, which was historically available at the famous Binion's Horseshoe Casino on Fremont Street
in Downtown Las Vegas. According to a relatively recent survey of craps odds, the only Las Vegas casino currently offering 100 times odds is Casino Royale.
