Hey Bunuel,
I am still not able to interpreted properly, so to better understand, I came up with my own question.
Suppose, there are 7 siblings pairs and a committee needs to be formed with only 3 members that does not include a sibling pair.
Total no of ways-
14c3- 4c1*12c1
728-84 = 644
Is this correct.
If it is. I got the trick.
If not, I still need to cope up
Please let me know.
