On a single roll is it 2/3.
1-2
Evens or 50/50 as either 2 or 4 or 6 (all divisible by 2) or 1 or 3 or 5 (not divisible by 2)
Well, numbers divisible by 2 are even numbers, and the even numbers from 1 to 6 are 2,4,and 6. Since there are 3 out of 6 even numbers on a number cube, there is a probability 1/2 to roll an even number on a number cube.
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
If you roll the die often enough the probability is near enough 1 so as to make no difference. On a single roll, the probability is 1/2.
If the die is fair then for a single roll, the probability is 1/2.

The probability of rolling a 2 is 1 in 6. The probability of rolling an even number is 3 in 6. The probability of doing both, on two rolls, is 3 in 36, or 1 in 12.
Prob(Sum is not divisible by 3) = 24/36 = 2/3
Probability of rolling an even number on a die is 1/2.
The probability of rolling an odd number on a standard die is 3 in 6, or 1 in 2, or 0.5.
The probability of rolling an odd number is 3/6 (or rather, 1/2), so the probability of rolling an odd number three times in a row is 1/2^3 is 1/8 or 12.5%.
