"At <a href=""https://www.youtube.com/watch?v=FJSI7QTAt_o&amp;t=38m38s"">38:38</a> Sophie just missed the chance to publicly reveal Mia's lie.<br>The only possibility to have 0 in the end would have been to have only Sophie put 1 dollar: $1 + 50% = $1",50, divided by 5 gives $0,30 rounded to 0.<br>If Mia really had put 1 dollar inside, then it would have been $2 (Sophie's and Mia's) + 50% = $3, divided by 5 gives $0,60 rounded to $1.<br>Being acknowledged as a liar, Mia could have potentially be the only one to not receive ⅕ of the briefcase... but who knows, it's fascinating to think about possible developments from that point on.<br><br>Brilliant show Tom, congrats to you and all your guests.
