Statistics question? 10 points

8,9,10,11,......
I am having a hard time in my statistics class because the teacher is horrible and the book is okay but I cannot find anything about this question. Please help?

Find the probability of rolling a number at least as great as 4 when rolling a 12-sided die.

-
no .of possibilities for a 12-sided dice = {1,2,3,4,5,6,7,8,9,10,11,12}
rolling a number at least as great as 4 = {4,5,6,7,8,9,10,11,12}

prob(rolling a number at least as great as 4) = 9/12
=3/4
