6 sided die probability to roll a odd number or a number less than 6

6 sided die probability to roll a odd number or a number less than 6

First, we'll find the set of rolling an odd number. From this dice calculator, we get:
Odd = {1, 3, 5}

Next, we'll find the set of rolling less than a 6. From this dice calculator, we get:
Less than a 6 = {1, 2, 3, 4, 5}

The question asks for or. Which means a Union:
{1, 3, 5} U {1, 2, 3, 4, 5} = {1, 2, 3, 4, 5}

This probability is 5/6
