Question

WS
-6) Find the number of differant ways
of arranging letters in the word ARRANGE​

Answer 1

Step-by-step explanation:

ARRANGE

A_ _ _ _ _ _ = 6!/2! = 6×5×4×3 = 360

We have divided by 2! as There are two R

R _ _ _ _ _ _ = 6!/2! = 360

Here A and R are repeated twice..

N _ _ _ _ _ _ = 6!/2!×2! = 180

G _ _ _ _ _ _ = 6!/2!×2! = 180

E _ _ _ _ _ _ = 6!/2!×2! = 180

So number of ways will be =>

360+360+180+180+180

720 + 360+180

1080 +180

1160 ways..
