Question

write sets x, y and XUY, XNY x-y, y-x from the given venn​

Answer 1

Answer:

Example:

Given U = {1, 2, 3, 4, 5, 6, 7, 8, 10}

X = {1, 2, 6, 7} and Y = {1, 3, 4, 5, 8}

Find X ∪ Y and draw a Venn diagram to illustrate X ∪ Y.

Solution:

X ∪ Y = {1, 2, 3, 4, 5, 6, 7, 8} ← 1 is written only once.

If X ⊂ Y then X ∪ Y = Y.

We will illustrate this relationship in the following example.

Example:

Given U = {1, 2, 3, 4, 5, 6, 7, 8, 10}

X = {1, 6, 9} and Y = {1, 3, 5, 6, 8, 9}

Find X ∪ Y and draw a Venn diagram to illustrate X ∪ Y.

Solution:

X ∪ Y = {1, 3, 5, 6, 8, 9}
