Question

look at the sets below (1,4,8,12)(2,4,6,8) which of the following shows the union of the sets? (4,8) (1,4,8,12) (2,4,6,8) (1,2,4,6,8,12)

Answer 1

Answer: (1,2,4,6,8,12)

Explanation:

Given sets : (1,4,8,12) and (2,4,6,8)

Let A =(1,4,8,12) and B=(2,4,6,8)

The union of any two sets contains all the elements of both sets A and B (no repetition).

Now, the union of the given sets will be :-

(1,2,4,6,8,12)

Hence, from the given questions, the union of sets is (1,2,4,6,8,12).

Answer 2

Set 1: {1,4,8,12}
Set 2: {2,4,6,8}

We have to find the union of these two sets. The union of two sets contain all the elements that are either present in one set or in both the given sets. In case an element is a member of both sets, it is mentioned only once while writing the union.

So, the union of the two sets will be: {1,2,4,6,8,12}
4 and 8 occur in both sets, but will be written just once in the union set.

So, the answer will be {1,2,4,6,8,12}
