Answer:
9! = 3,62,880 ways
Step-by-step explanation:
Number of sweaters= 4
No. of coats = 2
No. of jackets = 5
Total = 11
If she puts a sweater first and a jacket last, these two things have fixed places.
Now, number of sweaters = 4 (Since 1 sweater is placed in the first place)
No. of coats = 2
No. of jackets = 4 (Since 1 jacket is placed in the last place)
Total = 9
So, no. of ways in which these 9 things can be arranged = 9!
= 3,62,880 ways
Hence, these things can be arranged in 3,62,880 ways.
