Answer 2

Maximum possible number of ways of three item sets is equal to 35.

Explanation:

• Lets suppose the number f object to be chosen = r
• Total number of objects = n

Solution:

The maximum possible way of choosing the objects out of a total of n objects is equal to nCr.

nCr is equal to n! / (r! ( n - r ) ! )

For choosing three objects from seven objects, maximum possible ways is equal to 7C3.

The value of 7C3 is equal to 35.

Hence, the maximum possible ways is equal to 35.
