I need to find the theoretical probability of drawing 2 red cards that add up to 13, but there are some twists to this:

1) Find prob. with and without replacement

2) Jokers are included in the deck

3) Face cards have a value of 10 (a 3 and a king is the same as a 3 and a 10, and so on...)

4) Aces have a value of 1

5) Find the probability using events (fractions)

6) Find the probability using combinations (nCr)

I'm sorry that this is so much to ask for, but this is what i have to do for a paper (and 12 other problems similar to this one), ANY help at all will be appreciated.

-----------------

This is the work i have done so far (to the point where i am sure about, i have gone down many paths that lead to being clueless)

You can draw these choices:

King - 3

Queen - 3

Jack - 3

10 - 3

9 - 4

8 - 5

7 - 6

6 - 7

5 - 8

4 - 9

3 - 10

3 - Jack

3 - Queen

3 - King

11 cards*4 suits = 44

52 cards+2 jokers=54

So i have (44/54), now what is the correct way to do my second event?

And for combinations i have (52 C 44)*(n C r) / (52 C 2), what is my second combination?
