There are 52 cars in a deck.
1. we are talking about 2 cards here so it'd be: 2/52 = 1/26
2. it's one card so: 1/52
3. we are talking 4 cards for each suit. so 4x4=16
so it's: 16/52 (you should check if you can shorten that)
4. find out how many possibilities have the sum of 7 (lets call that number n). then it's n/36
5. I have no idea what the hell that **** is
