Step-by-step explanation:
Total number of books, n = 18
Number of books to be selected, r = 7
Since, the order of arrangement doesn't matter ;
We use the combination formula :
nCr = n! ÷ (n-r)! r!
18C7 = 18! ÷ 11!7!
18C7 = (18*17*16*15*14*13*12) ÷ (7*6*5*4*3*2*1)
18C7 = 160392960 / 5040
18C7 = 31,827 ways
