There are two mutually exclusive events A and B with P(A)=0.7 and P(B)=0.6. Find the probability of following: i) A and B both occur ii) Both A and B does not occur iii) Either A or B does not occur

Yes, I copied it correctly. I also know that this question is my assignment question and can have out of the box answer too. Because as far as I know for Mutually exclusive events A and B, P(A union B) = P(A) + P(B). But it is exceeding one over here. Please let me know if this question is incorrect, then on what grounds and if correct, then on what grounds.
