Question

If X = (6, 8, 15, 33, 65), Y = {8, 23, 51, 65, 69}, find the union of two set X and Y.

1. {6, 8, 15, 23, 33, 51, 65, 69}
2. {6, 8, 15, 33, 51, 69}
3. {6, 8, 15, 23, 33, 8, 51, 65, 69}
4. None of these

Answer 1

Correct Answer - Option 1 : {6, 8, 15, 23, 33, 51, 65, 69}

Given:

X = (6, 8, 15, 33, 65), Y = {8, 23, 51, 65, 69}

Concept used:

(X U Y ) = Number elements is present in either set A or set B. But the common elements should be taken only once

Calculation:

(X U Y) = {6, 8, 15, 23, 33, 51, 65, 69}

∴ {6, 8, 15, 23, 33, 51, 65, 69} The union of two set X and Y.

 

No element is repeated in the union of two sets.
