please elaborate



Its same as 4 people selecting 2 books each.

= 8C2*6C2*4C2*2C2 = 1260

You have 8 books and 4 people

= (fist person select 2 out of 8 books) *(second person select 2 out of 6 books) *(third person select 2 out of 4 books) *(fourth person select 2 out of 2 books) *
= 8C2*6C2*4C2*2C2 = 1260

Does this not result in 2520?
