In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
standard number die = 6 sides
probability odd number = ?
Step 02:
total sides = 6
odd numbers = 3
probability odd number = odd numbers / total sides
probability odd number = 3 / 6
probability odd number = 1 / 2
The answer is:
probability odd number = 1/2
