How many ways can 5 friends sit together at the movies in 5 seats?

ss7ja [257]

Answer:

120

Step-by-step explanation:

The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,

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

⇒ 5! / (5-5)!

⇒ 5! / 1!

⇒ 5!

⇒ 5 × 4 × 3 × 2 × 1

⇒ 120

<h3>Hence there are 120 ways by which 5 friends sit together at the movies in 5 seats. </h3>
