0 z6 l7 Y% P" ueveryday 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
9 M6 C6 J) v* Z/ ]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 oncetvb now,tvbnow,bttvb. r' r6 P$ \ Z0 { G: h4 C2 ]9 R. y) e
any solution proposed would be statistically impossible. |
