-- It has to be "more than 2".
2 is not more than 2, so 2 doesn't qualify.
-- It has to be "less than 4".
4 is not less than 4, so 4 doesn't qualify.
-- The only number that's "more than 2 but less than 4" is 3 .
A silly way to say it, but this part is asking for the probability of rolling a 3 .
Good luck !
