Detailed explanation-1: -The probability of rolling an even number is three out of six, or three-sixths. This fraction can be simplified as the numerator and denominator are both divisible by three.
Detailed explanation-2: -The probability of both outcomes is equal i.e. 50% or 1/2. So, the probability of an event is Favorable outcomes/Total number of outcomes.
Detailed explanation-3: -There are three even numbers on each die (2, 4, & 6). You have a 50-50 chance of rolling one of these numbers on a single die. This can also be written as 1/2. The chance of getting on even number on two dice is therefore 1/2 x 1/2… which is 1/4, or 25%.
Detailed explanation-4: -Dividing the numerator by three gives us one as three divided by three is equal to one. And dividing the denominator by three give us an answer two. Six divided by three equals two. This means that the probability of rolling an odd number on a fair dice is one-half.
