Question

2. 2. If A = {a, b, c, d} B = {b, c, d, e} C = {c, d, e, f} D = {d, e, f, g}, find
(a) A - B
(b) B - C
(c) C - D
(d) D - A
(e) B - A
(f) C - B

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}
