(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
 
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
 
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6) 
 
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6) 
 
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
 
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Count them.  It's the 9 red ways out of the 36 possible ways.
Make the fraction 9/36 and reduce it to 1/4, and that's the probability.

Then divide the fraction 1/4 out:

      0.25
    4)1.00
        8
        20
        20
         0

Then change the 0.25 to 25% by moving the decimal two places right and 
putting a % after it.
