## Homework Statement

If we throw with two dice a and b, than we make two spaces call them space A and B.

Space A = a+b and space B = a*b. Next the question there are a couple of questions:

1) What is the probability P(A > 7)

2) What is the probability P(B = odd)

3) What is the probability P( A n B)

4) What is the probability P(A u B)

My problem is question 3, I know how to get the answers on question 1 and 2 and question 4 is applying Bayes Rule. Could anybody explain me how to get the answer on question 3?

## Homework Equations

I placed the tables you get for A and B offcourse A is the first table and B is the second table. Below there are the answers.

## The Attempt at a Solution

Because we got P(A >7) and P(B = odd).

Now when i try to get P(A n B) = P(A) * P(B) = (5/12) * (1/4) = 5/48, but the answer above in the picture states the answer is 1/12. I dont understand how to get there. Even when I count all the numbers >7 and are Odd, i dont come on 1/12. I really woul like to understand what i am doing wrong.

I appreciate all the help, thanks in advance
