How Do You Calculate Expected Value in Blackjack?

To calculate expected value in blackjack, we need to first understand what blackjack is. Blackjack is a card game typically played with one or more standard decks of 52 cards.

The objective of the game is to beat the dealer’s hand by having a higher total than the dealer without exceeding 21.

There are a few different ways to calculate expected value in blackjack, but the most common method is to use basic strategy. Basic strategy is a set of rules that tell you the best way to play every possible hand in blackjack.

The first step in using basic strategy to calculate expected value is to find the probability of each possible outcome. For example, if you have a hand with a total of 12 and the dealer has a hand with a total of 2, the probability of winning is 4/13, or 30.77%. The probability of losing is 9/13, or 69.

23%. The probability of tying is 1/13, or 7.69%.

Once you have the probabilities of each outcome, you can multiply each probability by its corresponding payoff and add them all together. The payoff for winning is 1:1, so we multiply 4/13 by 1 and add it to the other probabilities. The payoff for losing is -1:1, so we multiply 9/13 by -1 and add it to the other probabilities. The payoff for tying is 0:1, so we multiply 1/13 by 0 and add it to the other probabilities.

This gives us an expected value of -0.23%.

This means that, on average, for every $100 you bet on blackjack, you can expect to lose about 23 cents. This may not seem like much, but over time it can add up!

So how do you use this information? If you’re a casual player who just wants to have some fun, then don’t worry about it too much! But if you’re serious about winning money at blackjack, then knowing how to calculate expected value can be a valuable tool in making sure you’re always making the best possible decision.
