Hello, could you explain me how to solve this task? I would be very grateful for your help.

Two dice are rolled. The red die has been loaded. Its probabilities are P(1) = P(2) = P(3) = P(4) = = and P(5) = P(6) = 7. The green die is fair. Let the event A be "the sum of the faces showing is an even number." Let the event B be "the sum of the faces showing is divisible by 3." (a) find P(A). (b) find P( B). (c) find P(An B)
