Probability Calculator

Find the probability of an event from favorable and total outcomes.

Calculated Output

Probability (%) 16.667

Probability 0.1667

Probability of NOT (%) 83.333

Formula: P = favorable ÷ total

Step-by-Step Breakdown

1. Values used:

2. Favorable outcomes = 1

3. Total outcomes = 6

5. Probability = 16.667%

6. Probability = Favorable outcomes / Total outcomes = 1 / 6 = 0.1667

7. Probability of NOT = 83.333%

Did this calculator solve your problem today?

The math behind it

P(event) = favorable outcomes ÷ total outcomes. The complement (NOT the event) is 1 − P.

Rolling a 4 on a die → 1 ÷ 6 = 16.67%.

Can probability exceed 1?

No — it ranges from 0 (impossible) to 1 (certain), i.e. 0% to 100%.
