Probability Calculator – Calculate Likelihood of Events

The Probability Calculator is an online tool that helps you quickly determine the probability of an event occurring. Probability measures how likely an event is to happen and is widely used in mathematics, statistics, and everyday decision-making.

What is Probability?

Probability is the measure of the likelihood of an event occurring, expressed as a number between 0 and 1, or as a percentage. The formula for probability is:

Probability (P) = Number of Favorable Outcomes / Total Number of Possible Outcomes

How to Use the Probability Calculator?

• Enter the total number of possible outcomes.
• Enter the number of favorable outcomes.
• Click the calculate button.
• The calculator will instantly display the probability as a decimal, fraction, and percentage.

Examples

• Rolling a die: Probability of getting 3 → 1/6 ≈ 0.1667 → 16.67%
• Flipping a coin: Probability of heads → 1/2 = 0.5 → 50%
• Drawing a red card from a deck of 52 cards → 26/52 = 0.5 → 50%
