The universal set U is the set of all odd numbers less than 20 and set

1.	The universal set U is the set of all odd numbers less than 20 and set A = {x : x is an odd multiple of 3 and x < 20}. Find complementary set A'.1. A' = {1, 5, 11, 13, 17, 19}2. A' = {1, 5, 7, 11, 13, 17, 19}3. A' = {1, 19}4. A' = {1, 2, 5, 7, 8, 11, 13, 16, 17, 19}
Answer» Correct Answer - Option 2 : A' = {1, 5, 7, 11, 13, 17, 19} Concept: If U is a universal set and A be any subset of U then the complement of A is the set of all members of the universal set U which are not the elements of A. It is denoted by A' A' = U - A Calculation: U = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19} A = {3, 9, 15} A' = U - A = {1, 5, 7, 11, 13, 17, 19}

The universal set U is the set of all odd numbers less than 20 and set A = {x : x is an odd multiple of 3 and x < 20}. Find complementary set A'.1. A' = {1, 5, 11, 13, 17, 19}2. A' = {1, 5, 7, 11, 13, 17, 19}3. A' = {1, 19}4. A' = {1, 2, 5, 7, 8, 11, 13, 16, 17, 19}

Answer» Correct Answer - Option 2 : A' = {1, 5, 7, 11, 13, 17, 19}

Concept:

If U is a universal set and A be any subset of U then the complement of A is the set of all members of the universal set U which are not the elements of A.

It is denoted by A'

A' = U - A

Calculation:

U = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19}

A = {3, 9, 15}

A' = U - A = {1, 5, 7, 11, 13, 17, 19}
