Question

2. Which of the following is
union of (1, 2, 5)and [1, 2, 6)?​

Answer 1

Answer:

1. The union of the sets {1, 2, 5} and {1, 2 , 6} is the set ... Which of the following two sets are disjoint? a) {1, 3, 5} and {1, 3, ...

Answer 2

The union of the sets {1, 2, 5} and {1, 2, 6} is the set {1, 2, 5, 6}

Given :

The sets {1, 2, 5} and {1, 2, 6}

To find :

The union of the sets {1, 2, 5} and {1, 2, 6} is the set

A. {1, 2, 6, 1}

B. {1, 2, 5, 6}

C. {1, 2.1, 2}

D. {1, 5, 6, 3}

Solution :

Step 1 of 2 :

Write down the given sets

Let A and B are the given sets respectively

Then

A = {1, 2, 5}

B = {1, 2, 6}

Step 2 of 2 :

Find union of the sets

We know that set is a well defined collection of distinct objects of our perception or of our thought to be conceived as a whole

The union of the sets {1, 2, 5} and {1, 2, 6}

= The union of the sets A and B

= { x : x ∈ A ∨ x ∈ B }

= {1, 2, 5, 6}

Hence the correct option is B. {1, 2, 5, 6}

Correct question : The union of the sets {1, 2, 5} and {1, 2, 6} is the set A. {1, 2, 6, 1} B. {1, 2, 5, 6} C. {1, 2.1, 2} D. {1, 5, 6, 3}
