A single die is rolled. Find the probability of rolling an even number or a number less than 4
5/6 because there are 5 possible possibilities and 6 numbers on the dice I'm assuming that the dice has 6 faces.
Even numbers on a dice: 2,4,6 = 1/2 chance.
Numbers less than 6 on a dice: 5/6 chance.
1/2 + 5/6 = 8/6.
8/6 is impossible so we'll take it down to 1. There will ALWAYS be an even number, or a number less than 6.
The answer is 1.
