Answer:
AUB = {Avocado, Coconut, Olive, Pear, Raspberry, Grape, Watermelon}
Explanations:
Note that:
A U B means the union of sets A and B
The union of two sets A and B is a set that contains all the elements that are either in A or B
From the question:
A = {Avocado, Coconut, Olive, Pear, Raspberry}
B = {Avocado, Grape, Olive, Watermelon}
Therefore, AUB will be:
AUB = {Avocado, Coconut, Olive, Pear, Raspberry, Grape, Watermelon}
