Contestants in a game show are each given four pairs of numbers (for example, 1 and 3, 5 and 4, and 6 and 1). A person in the audience is randomly picked and asked to roll two dice, one blue and one green. The blue die gives the first number in the pair, and the green die gives the second number. The probability that each player has of winning is?

Please give a good explanation on this one! Thanks!
