(1) There are six possibilities, and there are three shaded areas, so the probability is that the probability of Zhang Hong getting the admission ticket is 36 = 12, which is fair;

(2) draw a tree diagram:

According to the tree diagram, there are 3×3=9 possibilities, and there are 5 possibilities if the sum of the numbers on two cards is even, so the probability of winning the prize for Wang Wei is 59, and the probability of winning the prize for Zhang Hong is 49.49 < 59, which is unfair.
