Best ResponseYou've already chosen the best response.0I think it's more than that actually. Let's just consider that runner #1 finishes first : #1,#2,#3 #1,#2,#4 #1,#2,#5 #1,#2,#6 #1,#3,#2 #1,#3,#4 1,3,5 1,3,6, etc. etc. I'm not very good in probabilities, so I don't know what formula you should be using, but it's definitely more than 20
