Question

1. If A = {a, b, c), B = {b, c, d) and C = {a, b, c), then (A - B) x (B Π C) =

a) {(a, b), (a, c)}

b) {(a, b), (c,d))

c) {(c, a),(d, a))

d) {(a, c), (a, d), (b, d)}
​

Answer 1

Answer:

$\huge \underline{ \sf{ \red{given}}}$

A={a, b, c}

B={b, c, d}

C={a, b, c}

Find :- (A-B) ×(BnC)

Solution:-

(A-B) ×(BnC)

= ( {a, b, c} -{b, c, d} × {b, c, d} n{a, b, c}

=({a}×{b, c})

Answer 2

$\huge\bf\fbox\red{Answer:-}$

(A-B) ×(BnC)

= ( {a, b, c} -{b, c, d} × {b, c, d} n{a, b, c}

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