In starting he take 2 socks =if 1 is black and 1 is brown.
Know he needs 1 socks (black/Brown),
So 2+ 1=3.
The answer is 3.

Hi, the question says the word 'matching ' pair so needs to get either two black or two brown socks. Now if he draws and only two. It can be both black or both brown or one each of different color. So 2 is not the answer. But if he draws three he get either all three black or brown or 1 black two brown or 2 black one brown. I. Each case he will surely get a matching color. So 3 is the right answer.

Hi, according to me, It sounds impractical because one of the socks is going to be different leg.

If i take out 3 socks then it may be as follows;
black ---- brown
1 ---- 2
2 ---- 1.
Without this there is no combination. So one matching pair of socks must be. So the answer will be 3.
black ---- brown
1 ---- 2
2 ---- 1.
Without this there is no combination. So one matching pair of socks must be. So the answer will be 3.

A man wears a different colour of socks, he has to take another one (that is to be a matching for any colour of the other two that he is wearing) The question is how many socks to be taken out of a drawer to get a matching pair of sock. As we know, he is already wearing a pair of different colours, So. All he has to get is 3 socks.

6 individual socks are sitting in your drawer: two red, two blue and two purple. It's dark- you can't see.
You pick a first sock uniformly at random and then a second sock from the remaining five. Assume the two choices are independent.
What is the probability you end up with two socks of the same colour?
