how many different two player thumb-wrestling teams could be formed from 5 players?

let them be a->e

ab,ac,ad,ae,bc,bd,be,cd,ce,de = 10 combinations.

Exactly Right.

Also try: Combinations and Permutations Calculator (Order Important: No, Repetition: No), which gives:

"Combinations without Repetition (n=5, r=2)
{a,b} {a,c} {a,d} {a,e} {b,c} {b,d} {b,e} {c,d} {c,e} {d,e} "

For small problems that works fine.

But then ask how many different 4-player teams could be formed with 40 people, and you find that the mathematics becomes easier.

is it necessary for simle things to make it on difficult way it is as simple as nCr like so take a right step. definately it will increase the way of thinking for big nos.
