Answer
5/6
Work Step by Step
The probability of the given event has a complement of less than or equal to 4. (if you don't roll a 5 or more, you roll a 4 or less) Thus, the probability we roll a 4 or less is the favorable outcome $[(1,1)(2,1)(1,2)(3,1)(2,2)(1,3)]$ over the sample space of 36 events. $6/36 =1/6$
We are finding the complement or $1-1/6=\boxed {5/6}$
