The probability of rolling a #4# or greater is #1/2#.

Explanation:

When a cube with sides numbered #1# through #6# is rolled one time, the possible events are six i.e. getting #{1,2,3,4,5,6}#, with equal probability for each.

Of these, the events for which we get #4# or greater are #{4,5,6}# i.e. three events.

Hence probability of getting #4# or greater is #3/6=1/2#
