Answer 1

Answer: 6

Explanation:

Given, In a shoe rack there will be 3 shoes, 2 flip flops and 5 tennis shoes.

To find : Number of possible arrangements since the shoes of the same type are together side winged in the shoe rack.

For arrangement we use Permutations.

As the shoes of the same type are together , we consider the type of shoes for arrangement.

Number of ways to arrange them = 3! [By permutation]

= 3 x 2 x 1

= 6

So, the required number of ways = 6.
