Answer:
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.
