Question

A combination that would have the same answer as 250C247

Answer 1

Explanation:

Choosing 247 things from a 250 would have the same number of possibilities as choosing 3 things from 250.

250C247 = 2,573,000

and

250C3 = 2,573,000

*Notice 247+3 = 250

To generalize the situation,

xCy = xC(x-y)

Here we'd have

250C247 = 250C(250-247)

or

250C247 = 250C3
