Field Bet Analysis: Single Roll Bet Probability and House Edge

The field bet is a popular wager in craps that allows players to bet on any of the possible outcomes when a single die is rolled. The bet can be made by placing chips on the table in front of the boxman, and it’s known as the "any seven" bet because one of the winning combinations is a roll of 7 with https://rippercasinogameau.com/ two different numbers (e.g., 1-6 or 2-5). However, the field bet also covers other outcomes such as hardways (two identical numbers), easy ways (three consecutive numbers, like 3-4-5), and others. In this article, we’ll delve into the probability of winning a single roll field bet and calculate the house edge associated with it.

Probability of Winning

To determine the probability of winning, let’s first look at the possible outcomes when rolling a single die: 1, 2, 3, 4, 5, or 6. Since there are six possible outcomes and only one outcome is a win (rolling a 7 with two different numbers), the probability of winning on any given roll is relatively low.

The winning combinations for the field bet include:

  • Any seven (1-6 or 2-5)
  • Hardways (11, 22, 33, etc.)
  • Easy ways (three consecutive numbers: 3-4-5, 4-5-6, etc.)

Out of a total of six possible outcomes, only four combinations are winning outcomes for the field bet. Therefore, the probability of winning with the field bet is 4/6 or approximately 66.67%. However, this calculation doesn’t take into account the fact that there are multiple ways to win.

The most common way to win with the field bet is by rolling a "hardway," which occurs when two identical numbers are rolled (e.g., 11 or 22). There are six possible hardways: 11, 22, 33, 44, 55, and 66. Since there are only two ways to roll each of these combinations (e.g., 5-5 for a roll of 55), the probability of rolling any one of these hardways is 2/36 or approximately 5.56%.

Another winning combination is an easy way, which occurs when three consecutive numbers are rolled in a specific order (e.g., 3-4-5). There are ten possible easy ways: 1-2-3, 2-3-4, 3-4-5, 4-5-6, 5-6-7, 6-7-8, 7-8-9, 8-9-10, 9-10-11, and 10-11-12. Since there are only two ways to roll each of these combinations (e.g., 3-4-5 or 5-4-3), the probability of rolling any one of these easy ways is also 2/36 or approximately 5.56%.

The last winning combination for the field bet is rolling a seven with two different numbers (1-6 or 2-5). As mentioned earlier, there are only four possible combinations that result in a win: 1-6 and 2-5.

Calculating the Probability of Winning

Now that we’ve broken down the winning combinations for the field bet, let’s calculate the overall probability of winning with this wager. We can use the following formula to calculate the probability:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

For the field bet, there are 16 favorable outcomes: 1-6, 2-5, 11, 22, 33, 44, 55, 66, 1-2-3, 2-3-4, 3-4-5, 4-5-6, 5-6-7, 6-7-8, 7-8-9, and 8-9-10.

The total number of possible outcomes when rolling a single die is six. However, since we’re only considering the field bet with a single roll, we need to consider all possible combinations for each winning outcome.

For example, there are two ways to win with the combination 1-6 (rolling a 1 and then a 6 or vice versa). Therefore, we should calculate the probability of rolling any one of these combinations separately.

Using the formula above, we can calculate the overall probability of winning with the field bet as follows:

Probability = (16 favorable outcomes) / (Total number of possible outcomes)

There are six possible outcomes for each roll. Since there are 16 favorable outcomes and only four combinations that result in a win, we should recalculate the total number of possible outcomes to include all combinations.

The correct total number of possible outcomes is 6 * 6 = 36, since there are six possible outcomes when rolling one die (1-6), and six possible outcomes when rolling another die (1-6). However, since we’re only considering a single roll, the total number of possible outcomes is actually 6.

House Edge

The house edge for any wager is calculated by subtracting the probability of winning from 100%. The resulting percentage represents the proportion of money that the casino will win in the long run. To calculate the house edge for the field bet, we can use the following formula:

House Edge = (1 – Probability) * 100

Using the correct total number of possible outcomes and the overall probability of winning calculated above, we can determine the house edge as follows:

Probability = (16 favorable outcomes) / (36 possible outcomes) = 0.4444…

House Edge = (1 – 0.4444…) * 100 = 55.56%

Therefore, the house edge for the field bet with a single roll is approximately 55.56%. This means that in the long run, the casino can expect to win around $0.556 of every dollar wagered on this bet.

Conclusion

In conclusion, the probability of winning with the field bet when rolling a single die is relatively low due to the numerous possible outcomes and combinations that result in a loss. However, by breaking down the winning combinations for each outcome, we can calculate the overall probability of winning and determine the house edge associated with this wager.

While the house edge for the field bet may seem high at approximately 55.56%, it’s essential to remember that the casino’s advantage is built into the rules and odds of the game. As a result, players should be aware of the probabilities involved in any wager before placing their bets.
