Answer 2

Answer: A. 10

Step-by-step explanation:

$^nC_r=\dfrac{n!}{r!(n-r)!}$

Given : Five people want to rent the last two copies of a movie.

Then, the number of ways these 5  people rent the 2 movies is given by:-$^5C_2=\dfrac{5!}{2!(5-2)!}\\\\=\dfrac{5\times4\times3!}{2\times3!}=10$

Hence, these  five people can rent the two movies in 10 ways.
