There can't possible be a way, the reason being the following:
( ] s7 X4 ^# C" \) y0 |everyday 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: g" u( H: t. G, m8 U. d( u
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% q$ u+ D6 m, t; q3 E
any solution proposed would be statistically impossible. |
