I am stuck on a probability question.

Question

Please help and tell me the easiest way to find the answer to this..
I am confused and keep getting 5/6

A fair die is rolled..what is the probability of rolling an odd number or a number less than 3?

the actual answer is 2/3..
tell me how did you get here.. and what formula and what step to use.. what is the name of this method called.

Answer 1

1,3,5 are odd
1,2 are below 3
since 1 is in both groups you don't need to count it both times so it would be
1,2,3,5 meaning 4/6=2/3

Answer 2

4/6=2/3
