Suppose a laundry bag has many red,white and blue socks.Find the minimum number of socks that one needs to choose in order to get two pairs(four socks) of same color using pigeonhole principle

Answer 1

Answer:

So 10 socks need to be drawn

Step-by-step explanation:

red,white and blue socks are in laundry bag

Before getting two pairs ( four socks ) of same color

the person can get maximum 3 socks of each color

So

3 socks of red color

3 socks of white color

3 socks of blue color

after choosing 9th Socks then on choosing 10th Sock

it will be either of color from red,white and blue

So what ever color it is .  two pairs ( four socks ) of that color will be completed

So 10 socks need to be drawn
