Step-by-step explanation:

If A and B are two different events then, P(A U B) = P(A) + P(B) - P(A ∩ B)

Explanation of the formula:

If you look at the Venn Diagram, if you add 2 areas : P(A) and P(B), P(A ∩ B) is overlapping. This is why you should remove P(A ∩ B).

However, in this case, we should find P(A ∩ B) and all the other values are given in the question. Hence, we implement them and find P(A ∩ B).
