16)U={c, d, e, f, g, h,i,j} A={c, d, g, j} find A'.
17.) A={-3,-2,1,4} B={0,1,2,4} find A-B.​

Answer 1

Answer:

A  

′

=U−A

Given U={a,b,c,d,e,f,g,h}

(i) A={a,b,c}

A  

′

={d,e,f,g,h}

(ii) B={d,e,f,g}

∴B  

′

={a,b,c,h}

(iii) C={a,c,e,g}

∴C  

′

={b,d,f,h}

(iv) D={f,g,h,a}

∴D  

′

={b,c,d,e}
