Thank you for your reply..if twins are there..confirmed 2 girls
and boys are 6C2
if no twins so u take 5C2 (becuase girls are 7 and minus 2 twins so left 5 )
and that into 6C2 of the boys
therefore 6C2 + 6C2 x 5C2
I don't get one point here.. if the twins are there, won't the combination be 7C2 (of the girls) X 6C2 (of the boys)?
Why have you omitted the combination of the girls?
