Question

if A = {a,b,c,d} and B = {c,d,e,f} find n ( (a union b ) × ( a intersection b ) × ( a ∆ b ) ) .​

Answer 1

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}
