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:

  1. A fair die has 6 faces, numbered from 1 to 6.
  2. Each face has an equal probability of appearing.
  3. The total number of possible outcomes is 6.

The probability of rolling any specific number (e.g., a 1, 2, 3, etc.) is:

P(specific number)=16P(\text{specific number}) = \frac{1}{6}

So, the probability of rolling any particular number, say a 3, is 16\frac{1}{6}.

Key Details:

  • If you're looking for the probability of rolling an even number (2, 4, or 6), it would be 36=12\frac{3}{6} = \frac{1}{2}.
  • For rolling a number greater than 4 (either 5 or 6), it would be 26=13\frac{2}{6} = \frac{1}{3}.

Do you have any specific conditions or events in mind for the dice roll?
