P(A and B) = 3 is incorrect. It should be P(A and B) = 1/6
This is because there is one number in the overlapping region, and this is out of 6 numbers total.
The 2 & 4 are values that do not fit either event A or event B, such that
event A = rolling an odd number = {1, 3, 5}
event B = rolling a number that is a multiple of 3 = {3, 6}
however, the values 2 & 4 are still found on the die that is rolled, so they are listed outside the two venn diagram circles.
