Answer:
12/56
Explanation:
There are 56 cards in a deck. There are 10 total even red cards being the 2, 4, 6, 8, and 10 of diamonds, plus the 2, 4, 6, 8, and 10 of hearts. Since there are four sixes in every deck of cards, and we have already used two in the first part of the question, we add the other two now. This totals to 12/56 cards.
