Determine, for the sets

$M=\{a,b,c,d,e\},\,N=\{a,c,e\},\,P=\{b\},\,R=\{b,d,e,f\},$

the following sets.

1. ${}M\cap N$,
2. ${}M\cap N\cap P\cap R$,
3. ${}M\cup R$,
4. ${}{\left(N\cup P\right)}\cap R$,
5. ${}N\setminus R$,
6. ${}{\left(M\cup P\right)}\setminus {\left(R\setminus N\right)}$,
7. ${}{\left({\left(P\cup R\right)}\cap N\right)}\cap R$,
8. ${}{\left(R\setminus P\right)}\cap {\left(M\setminus N\right)}$.
