# Counting measure

Definition: For any E in X, where X is any set, define M(E) = infinity if E is an infinite set, and let M(E) be then number of points in E if E is finite. M is called the counting measure on X.

Let f(x) : R -> [0,infinity)

f(j) = { a_j , if j in Z, a if j in RZ}

( Z here is counting numbers, R is set of real numbers)

Let M be the counting measure. Find integral over R of f dM.
