Let the sample space be the outcome of rolling a single die: {1,2,3,4,5,6}. n(S)=6

Let the event be rolling a number less than 5.E= {1,2,3,4 }.n(E)= 4

Find the probability of the complement of this event.P(E^c)= ________

Note: Complement of first event is the outcomes not in E:E^c= {5, 6} .n(E^c)=2

The format of your answer is a fraction. (no need to simplify). for example:5/10
