4 C1 r0 v- O' E* }7 g8 ~, E) }0 geveryday 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, U& l$ {9 _( ?
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 once0 e7 k( @& d; C2 H
any solution proposed would be statistically impossible. |
