20 ¤ 20 = 400hands
*NB: each man stretched-forth only one hand to check (..for we dont check with both of our hands)
..thanx
BUT ... Sam shaking hands with Sue is the same as Sue shaking hands with Sam
__ so half of the handshakes are duplicates
(20*19)/2=190
{(AB), (AC), (AD), (BC), (BD), (CD)}
6 possible combinations
C(4, 2) = 4×3/(1×2) = 6
With n people there would be C(n,2) handshakes. With 20 people, there would be C(20,2) handshakes.
C(20, 2) = 20×19/(1×2)
= 190

Now Bros.. first of all, remember that they are 20men. When the 1st check the other 19men, it produces 19 hands; and the 2nd Man check the remaining 18 it produces 18 hands.
*Now this is how the prograssion continued till the result came down to only 1 hand. ..Now ADD up the whole result (ie: 19 + 18 +17 + ...+2+1 = 190).
*So, that will give you 190 hands from the 20 men in the room.
= 190hands

(A shaking hands with B is the same as B shaking hands with A) so 380/2=190 Handshakes.
Congratulations Gredo.Please email gistmeansu@gmail.com
Miracle Chizaram is still on our agenda. Please we still have you in mind.
20 multiplied by 19 equal to 380 handshakes.
