what is the probability of getting an even number when a dice is rolled?
The probability of getting an even number when a fair six‑sided die is rolled once is 12\frac{1}{2}21, or 0.5 (50%).
Quick Scoop
1. Step-by-step idea
A standard die has 6 faces: 1, 2, 3, 4, 5, 6.
Even numbers on the die are 2, 4, and 6, so there are 3 favorable outcomes out
of 6 possible outcomes overall.
Using the basic probability formula
P(even number)=number of even outcomestotal outcomes=36=12P(\text{even number})=\frac{\text{number of even outcomes}}{\text{total outcomes}}=\frac{3}{6}=\frac{1}{2}P(even number)=total outcomesnumber of even outcomes=63=21
So the answer is 12\frac{1}{2}21, which is the same as 0.5 or 50%.
Tiny story to remember it
Imagine rolling a die while playing a quick online forum game where people predict “even” or “odd” in real time. Half the people spam “even” in the chat, the other half “odd” — and that’s exactly how the math splits too: 3 even faces vs 3 odd faces, so half the time you expect an even result in the long run.
