Answer 1

The answer is P ∪ Q = {apples, oranges, banana, pears, graps} ⇒ c

Explanation:

Let us explain the meaning of the symbol "∪"

If A = {1, 2, 3, 4, 5} and B = {3, 5, 7, 9}

Then A ∪ B means all elements in A and B without repetition

Then A ∪ B = {1, 2, 3, 4, 5, 7, 9}

Let us solve the question

∵ P = {apples , oranges , bananas , pears}

∵ Q = {oranges , pears , grapes}

→ By using the rule above

∴ P ∪ Q = {apples, oranges, banana, pears, graps}

∴ The answer is P ∪ Q = {apples, oranges, banana, pears, graps}
