Let B ={the sum of the number cubes is divisible by 2}
Let A = {2,4,6,8,10,12}
Let B = {2,4,6,8,10,12}
</span><span>A ∩ B refers to intersection of events where A intersect B. Intersection refers to the sums that are common between that two events. These sums are both even and divisible by 2.
</span>
The outcomes in A ∩ B are <span>{2, 4, 6, 8, 10, 12}.
</span>All even numbers are divisible by 2.
