6 possible rolls
3 are even (2,4,6)
2 are less than 3 (1,2)
But one roll (2) is both
so there are 4 possible successful outcomes
P(success) = 4/6
If you are rolling a size sided number cube, what is the probability of rolling an even number or a number less than 3?

Each side is equally probable
5/6 are winners :)

sorry, 3 is NOT a winner of course
4/6 = 2/3
4/6 = 2/3
