It's called combinations...
Here's a link to brush up on http://www.themathpage.com/aPreC…
Also, if you have a Mac you can calculate this stuff with a program called longhand...
For 4 items, choosing 2 at a time (denoted 4C2), you get:
4!/((4-2)!*2!)= 6For 50 items, choosing 2 at a time, you get:
50!/((50-2)!*2!)= 1225Not quite as large as you guys are estimating, but it seems right to me. Even if you permutated this example, it would only be 3x as much.
Run it through your calculator and check me.
