Question

Form the union for the following sets.

X = {0, 10, 100, 1000)
Y = {100, 1000}
XUY=
A{}
B[100, 1000)
C {0, 10, 100, 1000)
D{0, 10)

Now I know that a

union: is a set that contains all elements of the considered sets

so would the answer be C?

Answer 1

Yes, the answer would be C

Explanation:

Start with set X: {0, 10, 100, 1000}.

Add the elements from set Y to set X: {0, 10, 100, 1000, 100, 1000}.

Remove any duplicate elements: {0, 10, 100, 1000}.

The union of sets X and Y is {0, 10, 100, 1000}.
