See if they can both happen at the same time. If they can, it's not mutually exclusive.

If the spinner has any odd numbers greater than 6 on it, then they are not mutually exclusive.

And P( A or B) is P(A) + P(B) - P(A and B).

If they are mutually exclusive, P(A and B) is zero

so P(A or B) is just P(A) + P(B)

mutually exclusive means that they can not happen at the same time. They can't share any outcomes.

So A does include number greater than 6, only odd

and B includes odd numbers greater than 6 so I would say no those two outcomes are not disjoint.
