expected number of matching pairs
E[M_109] = C(n,2)/365 = 16.126  (16)

Var[M_109]=16*(1-1/365) < 16

Pr{|M_109-16| >= x} < 16/x^2

x=6:   probability of 10-22 pairs is > 50%
but we had only 3 pairs.  so x=13
Pr{|M_109-16| >= 13} < 16/169    
     so < 10% chance that the number of pairs was 0,1,2,3, or 29 or higher
