Control: A - n=18, B - n=0, C - n=0, D - n=0

Experimental: A - n= 3, B - n=20, C- n= 0, D - n=0.

What I want to show is that in the experimental case, the number falling into B is stat sig. (which just looking at the numbers seems pretty clear to me), but nonetheless I need to do a test on it.... I'm just not sure what to do..???
