How many increasing permutation of m symbols are there from the set of n numbers{a1,a2,...,an} where the order among the numbers is given by a1 < a2 < a3... < an?
We can choose m of of the n terms in C(n,m) ways.

That's the combinations of n things taken m at a time, sometimes
written nCm of  and the
formula for it is .
