In a shop, there are five types of ice-creams available. A child buys six ice-creams.
Statement-1: The number of different ways the child can buy the six ice-creams is `.^(10)C_(4)`.
Statement-2: The number of different ways the child can buy six ice-creams is equal to the number of different ways to arranging 6A's and 4B's in a row.

Explanation

possible ways`.^(n+r-1) C_(r-1)`

`= .^(6+5-1) C_(5-1)= .^10 C_4`

2)`.^10 C_6 * 1*1 = .^10C_(10-6) = .^10 C_4`
