Two people are playing with a pair of dies. Instead of numbers, the dies have different colors on their sides. The first person
wins if the same color appears on both the dies and the second person wins if the colors are different. The odds of their winning
are equal. If the first dice has 5 red sides and 1 blue side, find the colour(s) on the second one.

• let second dice have x red face & 6-x blue face
  p(a)=1-p(a)
  2p(a)=1
  2((5/6)(x/6)+(1/6)(6-x/6))=1
  x=3
