There are 10 black socks and 10 white socks in a drawer. Socks of the same color are identical but not allowed to look into the drawer while taking out socks.

**So, the task is to find the minimum number of socks to be drawn at random to be sure that he/she gets the pair of socks of the same color?**

**Answer:** 3

**Explanation:**

**Case 1:** Same sock color come out in 1st and 2nd attempt-

1st- Black

2nd- BlackOR

1st- White

2nd- White

**Number of removals = 2**

**Case 2:** Different color of socks come out in first and second attempt-

1st- Black

2nd- White

OR

1st- White

2nd- Black

In the third attempt, a black or a white sock come out, either way, a pair is completed.**So, the number of removals = 3**
