### 52 Card Pickup

A standard pack of cards is thrown into the air in such a way that each card, independently, is equally likely to land face up or face down. The total value of the cards which landed face up is then calculated. (Card values are assigned as follows: Ace=1, 2=2, ... , 10=10, Jack=11, Queen=12, King=13. There are no jokers.)

What is the probability that the total value is divisible by 13?

### From 18 to 29

Seems like a good day to equate things:

18 = H on a G C.
20 = F O in a P.
20 = H in a T.
21 = G S.
21 = D on a D.
23 = P of C in H.
24 = H in a D.
24 = C in P G.
26 = L of the A.
27 = B in the N T.
29 = D in F in a L Y.
