Perform the given set operation. Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. (Enter your answers as a comma-separated list. Enter EMPTY for the empty set.)
{1, 2, 8} ∩ {2, 8, 9}
you want the set of elements common to your two sets. So, which numbers are in both lists?
To perform the given set operation {1, 2, 8} ∩ {2, 8, 9}, we need to find the intersection of both sets.
The intersection of two sets is the set of elements that are common to both sets.
In this case, we have the sets {1, 2, 8} and {2, 8, 9}. To find the intersection, we need to identify the elements that are present in both sets.
Looking at the sets, we see that the elements 2 and 8 are common to both sets. Therefore, the intersection of {1, 2, 8} and {2, 8, 9} is {2, 8}.
So, the answer to the given set operation is {2, 8}.
