Q.

What is the total no of ways of selecting atleast one item from each of the two sets containing 6 different items each?

View Answer

Correct choice: B

Explanation:

We can select atleast one item from 6 different items = 26−1 Similarly we can select atleast one item from other set of 6 different items in 26−1 ways. Required number of ways = (26−1)(26−1) = (26−1)2 = 3969
