16. Perform the set operations

If \(K\) \(=\) \(\{\)\(e\), \(l\), \(p\)\(\}\), \(L\) \(=\) \(\{\)\(b\), \(e\), \(l\), \(y\)\(\}\), \(M\) \(=\) \(\{\)\(i\), \(l\), \(o\), \(p\), \(y\)\(\}\), then find the following:

 

(i) \(K\) \(\cap\) \(L\) \(=\) \(\{\)\(\}\).

 

(ii) \(L\) \(\cap\) \(M\) \(=\) \(\{\)\(\}\).

 

(iii) \((\)\(K\) \(\cap\) \(L\)\()\) \(\cup\) \((\)\(L\) \(\cap\) \(M\)\()\) \(=\) \(\{\)\(\}\).
