Answer:

A ∩ B = {12}

Step-by-step explanation:

What are the possible even outcomes?

Assuming the number cubes are 1-6,

our possible outcomes run from 2-12, but we are looking for even rolls, so A={2,4,6,8,10,12}.

How many of those are divisible by 3? B={12}.

We are looking for what is in common between these, so

A ∩ B= {12}
