Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

If U = {a, b, c, d, e, f, g} and A = {a, c, d, f} then which of the following set is A'

1. {a, c, d, f}

2. {b, e, f, g}

3. {a, b, c, d, e, f, g}

4. {b, e, g}

EVALUATION

Here the given universal set is

U = {a, b, c, d, e, f, g}

The set A is given by

A = {a, c, d, f}

Hence A'

= The complement of A

= { x : x ∉ A }

= { b, e, g }

FINAL ANSWER

Hence the correct option is 4. {b, e, g}
