What is the probability of rolling a number cube and getting an even number or an multiple of 3

The probability of getting even is 3/6 or 1/2 (mark as brainiest)

There are 6 numbers on a number cube:
1, 2, 3, 4, 5, 6
The even numbers are:
2, 4, 6
The multiples of 3 are:
3, 6
Those 2 groups of numbers together are:
2, 3, 4, 6
Divide 100 by 6 because there are 6 numbers.
100 / 6 = 16 2/3
Then multiply that by 4 because there are 4 numbers that we found.
6 2/3 x 4 = 66 2/3
So the answer is one of the following:
1. 66 2/3%
2. 66.66666666666...%
3. 67%

Idon’t know how to do that
