Calculating the Probability of Rolling an Odd Number on a Die

To find the probability of rolling an odd number on a fair six-sided die, we can use the formula:

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

In this case, the favorable outcomes are the odd numbers on a die, which are 1, 3, and 5. The total number of possible outcomes is 6, as there are six sides on a standard die.

Calculation

Using the formula, the probability of rolling an odd number on a fair six-sided die is: Probability = 3 (favorable outcomes) / 6 (total possible outcomes) = 1/2

Therefore, the probability of rolling an odd number on a fair six-sided die is 1/2 or 50%.

This calculation is based on the assumption that each side of the die has an equal probability of landing face up.
