Probability of rolling a prime number on a six-sided die

To calculate the probability of rolling a prime number on a six-sided die, we need to determine the number of favorable outcomes (rolling a prime number) and the total number of possible outcomes (rolling any number from 1 to 6).

Favorable outcomes

A prime number is a number greater than 1 that is divisible only by 1 and itself. On a six-sided die, the prime numbers are 2, 3, and 5. Therefore, there are 3 favorable outcomes.

Total outcomes

On a six-sided die, there are 6 possible outcomes, which are the numbers 1, 2, 3, 4, 5, and 6.

Calculating the probability

The probability of an event occurring is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

In this case, the probability of rolling a prime number on a six-sided die is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 3 / 6

Simplifying the fraction, we get:

Probability = 1 / 2

Therefore, the probability of rolling a prime number on a six-sided die is 1/2 or 0.5.
