# The addition rule says that if a finite set A equals the union of k distinct mutually disjoint subsets A 1 , A 2 , ... A k , then _________

To determine

To fill in the blanks of the given statement “The addition rule says that if a finite set A equals the union of k distinct mutually disjoint subsets A1,A2,...Ak, then ……….”

Explanation

Given:

The incomplete statement “The addition rule says that if a finite set A equals the union of k distinct mutually disjoint subsets A1,A2,...Ak, then ……….”

Concept used:

If A and B are two disjoint sets, then the number of the elements in AB equals the sum of the numbers of elements in A and the numbers of elements in B.

Let’s assume that finite set A equals the union of k distinct mutually disjoint subsets A1,A2,
