Consider a system of two particles A and B. Each particle can occupy one of three possible quan-
tum states j1i, j2i, and j3i. The ratio of the probability that the two particles are in the same state
to the probability that the two particles are in di_erent states is calculated for bosons and classical
(Maxwell-Boltzman) particles. They are respectively
a) 1; 0
b) 1=2; 1
c) 1; 1=2
d) 0; 1=2
