There can't possible be a way, the reason being the following:
! h+ N' G( c; a* e% F8 d }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
, N% S5 o% c0 x9 P. p6 vtvb now,tvbnow,bttvblets 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% n$ b+ J/ [9 y0 _- ?* v( q3 _
any solution proposed would be statistically impossible. |
