Math Problem Statement
What is the probability of a dice cast once
Solution
The probability of any outcome on a single roll of a fair six-sided die is calculated as follows:
- A fair die has 6 faces, numbered from 1 to 6.
- Each face has an equal probability of appearing.
- The total number of possible outcomes is 6.
The probability of rolling any specific number (e.g., a 1, 2, 3, etc.) is:
So, the probability of rolling any particular number, say a 3, is .
Key Details:
- If you're looking for the probability of rolling an even number (2, 4, or 6), it would be .
- For rolling a number greater than 4 (either 5 or 6), it would be .
Do you have any specific conditions or events in mind for the dice roll?
