It basically means that if there are n items and u have to put them in (n-1) boxes then at least one box must have more than one item.

this is very useful

Here's a practical problem

for eg if u want to prove that there are at least two animals in world having same amt. of hair then u can use this principle to prove it

1.let's get the average no of hairs on animal body(n2)

2, then no of animals(n1)

now If n1>n2 then atleast two animals will have same amt of hair on theor body
