Probability- Union and Intersection

[Mere]

I need help with an intersection problem. I have listed the values and the question below. If someone could please explain how to do this problem I would be very, very happy!

P(A)= 0.6
P(B)= 0.55
P(A n B)= 0.35

Find: P(A n (not B))

P(A)= 0.6
P(B)= 0.55
P(A n B)= 0.35

Find: P(A n (not B))

Do you have a rule for complementation? Maybe something like P(A) = P(A-and-B) + P(A-and-(not-B))?

They've given you P(A) and P(A-and-B), so I think you have the necessary information.
