Pls help!!
They need to form committee of only 5 members, so out of 8 you need to pick only 5
YYYYYNNN, 5Y indicates selected candidates and 3N indicates those who were not selected...so that turns out to be simple arrangement problem with 5 like and 3 like terms - 8!/(5!*3!)
Hope it helps, regards
