This is because there is only one "5" and one "6" in a dice. Moreover the total number of numbers in a dice are 6 so the denominator will be 6. Then when the word 'or' is present it means that both the probabilities must be added.
P (of rolling a 5 or 6 on a fair dice) = +
can be simplified further. Both 2 and 6 are factors of 2 so..
=
P (of rolling a 5 or 6 on a fair dice) =
