A drawer contains 12 identical white socks, 18 identical black socks and 14 identical brown socks. What is the least number of socks you
must choose, without looking, to be certain that you have chosen two socks of the same colour?

4 socks

Step-by-step explanation:

Lets see.

If you chose three socks, you might get 1 or white, 1 or black, and 1 of brown.

So if you chose 4, you have to get two socks of the same colour.

Hope this helps plz hit the crown :D

2 brown

Step-by-step explanation:

The only time you can be so sure you've chosen 2 brown socks is when there are no more white socks and black socks. This means that to be 100% sure that you have chosen 2 brown socks you have to choose the 12 white socks and the 18 black socks and only then can you choose 2 brown socks without looking. Therefore, the total number of socks to choose from is:

Total number of socks = 12 white socks + 18 black socks + 2 brown socks

Total number of socks = 32 socks

A total picking of 32 socks is necessary to be sure without looking that 2 brown have already been chosen that way.
