Question 10647
 The possibility of a hand of bridge is C(52,13).

 Among a deck of 52 cards, there are 32 =(8*4) cards between 2 & 9.
 So, there are C(32,13) possibilities of a yarborough hand.

 Hence, the probability for a yarborough hand is
  C(32,13)/C(52,13) [ you can leave the answer like that]
   = 0.000547033  [by using the function combin(n, r) in MS Excel ]
