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
