Do you have to know the ways though???

Mercury:

combination formula nCr, where n is the # of items you're choosing from (in this case, n = 8) and r is the # of items being chosen out of the group (in this case, n = 2) nCr = n! / (r! * (n-r)!)) = 8! / (2! * (8-2)!))

malakayman1:

Mercury:

Please refer to my previous response. If something was unclear I am happy to explain.
