Enter the total number of sectors and the number of winning sectors into the calculator to determine the probability of landing on a winning sector in a wheel game.

Wheel Probability Formula

The following formula is used to calculate the probability of landing on a winning sector in a wheel game.

P = (WS / TS) * 100

Variables:

  • P is the probability (%) of landing on a winning sector
  • WS is the number of winning sectors on the wheel
  • TS is the total number of sectors on the wheel

To calculate the probability, divide the number of winning sectors by the total number of sectors and then multiply by 100 to get the percentage.

What is Wheel Probability?

Wheel probability is the likelihood of the spinner landing on a winning sector in a game involving a spinning wheel. This concept is commonly used in games of chance, carnival games, and decision-making processes. The probability is determined by the ratio of winning sectors to the total number of sectors on the wheel.

How to Calculate Wheel Probability?

The following steps outline how to calculate the Wheel Probability.


  1. First, determine the total number of sectors on the wheel (TS).
  2. Next, determine the number of winning sectors on the wheel (WS).
  3. Next, gather the formula from above = P = (WS / TS) * 100.
  4. Finally, calculate the probability (P) of landing on a winning sector.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Total number of sectors on the wheel (TS) = 50

Number of winning sectors on the wheel (WS) = 10
