Answer :

Given: the total number of books = 4


To find: Number of ways in which these 4 books can be arranged in a shelf


Formula used:


Number of arrangements of n things taken all at a time = P(n, n)



The total number of ways


= the number of arrangements of 4 things taken all at a time


= P(4, 4)




{ 0! = 1}


= 4 × 3 × 2 × 1


= 24


Hence, Number of ways in which these 4 books can be arranged in a shelf are 24
