We take a uniformly random permutation of a standard deck of 52 cards, so
that each permutation has a probability of 1/52!. De fine the following events:
 A = \the top card is an Ace",
 B = \the bottom card is the Ace of spades",
 C = \the bottom card is the Queen of spades".
Determine
Pr(A | B);
and
Pr(A|C):

What is the meaning of "one equals fifty-two factorial"?

What is the meaning of the letter "J" between the "event" letters? I'm familiar with a "pipe" character, indicating "given" (such as "Pr(A|B)" which means "the probability of A, given B"), but not your notation. Thank you.
