Question 1079327

4/30*26/29*25/28*3, because the it could be 26/30*25/28*4/27 or 26/30*4/29*25/28--same results but they have to be added.
0.3202
or
denominator 30C3=4060
numerator 4C1*26C2=1300, and 1300/4060=0.3202.
---------------
At least 1: find 0 and subtract from 1. That would be 26/30/25/29*24/28=0.6404.
So at least 1 is 1-0.6404=0.3596.
