Question

Arun · Answer

Dear student We are to choose 4 persons for each side. As 3 persons lan row only on the stroke side, therefore, number of ways in which we can choose 4 persons for the non stroke side = = 9 C 4 Having done this we are left with 8 persons, so we can choose 4 persons for the stroke side in 8 C 4 ways. Hence Required number of arrangements = 9 C 4 * 8 C 4 * 4! * 4! Regards Arun (askIITians forum expert)
