there are six sides of a dice, numbered one through six. 5 and 6 are greater than four, so there is a 2/6 chance that you will roll a number greater than 4, or 1/3. multiply 72 times 1/3 and that equals 24. 24 out of the 72 (24/72 = 1/3)times is how much you could expect to get a number greater than 4.
