Tossing a number cube numbered from 1 to 6 and getting an Evan number that is greater than of equal to 2

Even numbers on die: 2,4,6

odd numbers on die: 1,3,5

3+3=6 - > 6 numbers in total

3/6 chance because there are 3 even numbers. This would round to 1/2, so 1/2 a chance the die will roll an even number.
