C(2,7)=21
thats correct @mukushla but where does the 2 come from?
is it because person A shakes hands with person B And then person B shakes hands with person A
One can shake 6 so there are 7 by 6 but this counts a single handshake twice.
^they can't shake hands twice
oh i see so why is it 7C2?
like i get how you say its like 6+5+4+3+2+1 =21 which is the same ans as 7C2
