Question

19.If A= {b,c,e,g,h}, B={a,c,d,g,j} and c={a,d,e,g,h}then show that A-(B ∩ C) = (A-B) U (A-C)​

Answer 1

Step-by-step explanation:

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}
