Question

Presley has 6 books. There is enough space on a shelf for 4 books. In how many ways can 4 of the 6 books be arranged on the shelf?

Answer 1

same idea as last time just with 4 slots this time (A,B,C,D)

6 choices for slot A
5 for B
4 for C
3 for D

6*5*4*3 = 30*12 = 360 different arrangements

order matters in this case

Answer 2

Thank you!
