Question

A,B,C are three finite sets such that n(A)=17,n (B)=13,n(C)=15,,n(AnB)=9,n(BnC)=4,n(CnA)=5and n(AnnBnnC)=3. Also n(U)=50
1) n(a intersection b intersection c')
2)n(b intersection c intersection a')
3)n(c intersection a intersection b')
4)n(a U b U c)
5)n(a U b U c')
plz ans fast and clearly
