Answer: Choice B) {2, 4, 6}
Step-by-step explanation:
The upside down U symbol represents an intersection. In other words, we want to find the numbers that are in both set D and set F at the same time.
Set D is the set of all whole numbers.
Set F is the set of even numbers from greater than or equal to 2, but less than 9.
Set D looks like this D = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ...}
Set F looks like this F = {2, 4, 6, 8}
We see that 2,4,6,8 is in both set D and set F at the same time, so therefore this is the intersection of the two sets.
side note: Set E isn't used at all so we can ignore it.
