Question

if u = {a,b,c,d,e,f} is the universal set and a,b,c are subsets of u where, a={a,c,d} , b U c= {a,b,e,f}. find a(b' n c')

Answer 1

Answer:

ANSWER

We know that complement of set A is 

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}
