    p(both cubes even) =

    p(red cube even) * p(blue cube even) =

    1/2 * 1/2 =

    1/4

    My red cube has sides with a white dot, a picture of a lion, a picture of a quarter moon, a trident, the outline of a human head, and a blank side. Which of those would you count as "even"?

    The blue cube has images of a flower, a spiral, a sword, a closed fist, a waterfall (very detailed with fine lines), and the the number 372.

    Do you mean red and blue dice ?

    Well .. the chances that each one is even is 50:50, which is 1 in 2 .... 1/2

    So the probability that BOTH are even is 1/2x1/2 .... 1/4 .... 1 in 4

    The colours have nothing to do with the result.

    1/4  <<<  answer

    there are 3 even numbers on a cube with 6 sides

      P one cube is even  =  3/6  or 1/2

      P both are even  =  1/2 X 1/2  =  1/4
