Greek "who wants to be a millionaire" failed on this one. The number of handshakes between n people is n(n-1)/2. For n=7, the correct answer is 21.

I majored in Popular Dulcimers of the 17th Century, so I'm out.

Would this formula also work ? ... Seven people shaking hands... 7*7 "equals 49" now the total minus the original.... 49-7 =42.. so the total times itself, minus it's initial amount, equals the overall total ... 42

Maybe they counted the left handed handshakes as well.

I guess it depends on how/ why you're shaking hands

If n(n-1)/2 and n =7 7(6)/2. PEMDAS 7*6 = 42/2. Huzzah!

Without big math you can just use common sense: first person does 6 handshakes, second 5, third 4, and so on until 0 for the last one, 6+5+4+3+2+1 handshakes in total

well, my "common sense" works best when I'm not on TV and when I've got enough time to think... sooo, I would have failed and had to live the rest of my life in shame...

Yup! This episode was broadcasted yesterday. I was very surprised they got it so wrong

This guy shakes with both hands

Which is what is being asked to be honest. Nobody said we are limited to one hand handshake. Between 2 persona we can do 2 handshakes, so while the question could be more clear it is not necessarily wrong
