There can't possible be a way, the reason being the following:
8 H) G _$ I& G5 e6 G) heveryday the person being picked is randomly generated, that means for a person to have 99.99% chance of being picked that takes over 600 days! m9 Z: Z( ?, C( u4 V
lets just assume only 2 person in the entire group is the unlucky one, and that would case over 4 years of time just to get everybody out in the yard once. w; J% U2 O: f7 B
any solution proposed would be statistically impossible. |
