67
78
44

405

You divide "405" by the amount of numbers there are.

so "5" into "405"
5 goes into 40 8 times
now we have 5 into 5 which goes 1 time.

To check our work, we can multiply 81 by 5.
5*1=5
5*8=40
405.

There are

$\dbinom{2n}2 = \dfrac{(2n)!}{2! (2n-2)!}$

ways of pairing up any 2 members from the pool of $2n$ contestants. Note that

$(2n)! = 1\times2\times3\times4\times\cdots\times(2n-2)\times(2n-1)\times(2n) = (2n-2)! \times(2n-1) \times(2n)$

so that

$\dbinom{2n}2 = \dfrac{(2n)\times(2n-1)\times(2n-2)!}{2! (2n-2)!} = \boxed{n(2n-1)}$
