Question

When rolling a fair number cube with numbers 1 through 6, what is the probability of rolling a number greater than 4?

Answer 1

If you include 4 the probability is 3/6 or 1/2. If 4 is not included it is 2/6 or 1/3. When four is included the possible numbers included are 4,5 and 6. If 4 is not included the possible numbers are 5 and 6.
