Number of Monotonic function
Consider a function F from set A to B having A={1,2,...n} and B={1,2,....m} Find number's of f in F where f is defined as : 1. f(i)<=f(j) and 1<=i<=j<=n 2.f(i)< f(j) and 1<=i<=j<=n 3. f(i) >=f(j) and 1<=i<=j<=n 4. f(i) > f(j) and 1<=i<=j<=n.

Combinatorics
It is required to divide the 2n members of a club into n disjoint teams of 2 members each. The teams are not labelled. The number of ways in which this can be done is: (A) (2n)! / 2n (B) (2n)! / n! (C) (2n)! / 2n · n! (D) n! / 2
