A = {red, green, blue, yellow} B = {orange, purple, black, blue} Find A U B.

{blue}

Step-by-step explanation:

I took the test

A∪B={ red, green, blue, yellow, orange, purple, black }

Step-by-step explanation:

Let A and B be two subsets Then A∪B represents the union of the two subsets which means that it consists of the elements present in A or B or in both A and B.

given A={ red, green, blue, yellow }

B={ orange, purple, black, blue }

Now A∪B={ red, green, blue, yellow, orange, purple, black }

for getting above first write all the elements in A then start writing elements of B and skip those elements of b which are already present in A and write all the elements of B.
