Question

(iv) If T={1,2,3,4,5) and M = {3,4,7.8) then T U M=?
(A) {1,2,3,4,5,7 (B) {1,2,3,7,8)
(C) (1, 2, 3, 4, 5, 7, 8) (D) (3,4)​

Answer 1

Answer:

c ) {1,2,3,4,5,7,8} union means elements of both set

Answer 2

The correct answer is option (C) {1, 2, 3, 4, 5, 7, 8}.

Given:

Two sets, T={1, 2, 3, 4, 5} and M = {3, 4, 7, 8}.

To Find:

T U M =?

Solution:

We have been given two sets T = {1, 2, 3, 4, 5} and M = {3, 4, 7, 8}. We are asked to find the union of the two sets, T U M.

The union of two sets is the collection of every element present in the two sets.

The elements of T are 1, 2, 3, 4, 5, and the elements of M are 3, 4, 7, and 8.

Collecting the elements of T and M together, we have the elements 1, 2, 3, 4, 5, 7, and 8.

Hence T U M = {1, 2, 3, 4, 5, 7, 8}.

∴ The correct answer is option (C) {1, 2, 3, 4, 5, 7, 8}.
