John is about to roll a six sided fair number cube 60 times he wants to predict how many times the cube will land on an even number he makes a prediction of 20 times is it a good prediction what would your prediction be based on theoretical probability

                  2x^2 + 5x + 2
3x^2 + 2    6x^4 + 15x^3 + 10x^2 + 10x + 4
             -    6x^4                + 4x^2
                             15x^3 + 6x^2 + 10x + 4
             -               15x^3            + 10x
                                           6x^2 + 4
                                           6x^2 + 4

Therefore, (6x^4 + 15x^3 + 10x^2 + 10x + 4) ÷ (3x^2 + 2) = 2x^2 + 5x + 2
