Blackjack and the Law of Independent Trials

What do dice rolls, the spin of roulette wheels, and the spin of slots reels have in common? All of these are subject to what we call the law of independent trials. Simply put, each of these things, like the dice rolls you make in craps for example, are completely independent of any other event. So it doesn't matter how many times you shoot the dice, the next toss will not be affected by the previous toss.

By abiding by the law of independent trials casinos make a lot of profit. Casinos make their money through their house edge not to mention that some games or bets have lopsided odds. Games like roulette and slots are pure games of chance subject to the law of independent trials. It is interesting that slots is a major contributor to a casino's profit since many people play them. It is either that many players are unaware of the law of independent trials or are just ignoring the potency of this law and are caught up in their game.

Fortunately, there are casino games that are not subject to the law of independent trials. One prime example of such a game is blackjack. In blackjack, you have a fixed number of decks though the total number of decks used at a table varies. As the game progresses the type of cards that will be dealt later is influenced by what cards have already been dealt earlier. If a lot of low numbered cards were dealt earlier in the game then you can expect to find more high numbered cards showing up later.

The rules of the game also help make things work for players in blackjack. Doubling down, splitting, get paid three to two when you get a blackjack makes this game more favorable for players compared to games of pure chance. It is interesting to note that these rules weren't there when blackjack was first introduced. The house edge back then was about seven percent or even a lot higher. The addition of the said rules lowered the house edge and made the game more player friendly.

Players can take advantage of the absence of the law of independent trials in blackjack by improving their playing skills. They can make the house edge go down even further using basic strategy. It is a player's skill not the law of independent trials that has a direct effect on the outcome of a game.

Another important tool that any blackjack player can put to good use is card counting. If a player is able to tell if there are more high valued cards left on the deck then that player has the advantage. Learning to count will take some time however. The absence of the law of independent returns, and its effects, in blackjack is an advantage no one should miss.
