Answer

5/6


Explanation

Probability is a chance of an event taking place.

Probability = (favorable outcome)/(total outcome)

There are 3 even sides in a dice.

P(even) = 3/6

           = 1/2

There are 2 numbers that are greater than 4 in a dice

P(x>4) = 2/6

          = 1/3

P(even or x>4) = 1/2 + 1/3

                          = 5/6
