Let U = {9, 10, 11, 12, 13, 14, 15}, A = {9, 10, 11, 12}, B = {9, 10, 13, 14}, and C = {11, 13, 15}. List all the members of the given set. (Enter your answers as a comma-separated list.)

(A �¾ B) �¿ C

Not sure what your characters are, but

(A∩B)∪C = {9,10}∪{11,13,15} = {9,10,11,13,15}

(A∪B)∩C = {9,10,11,12,13,14}∩{11,13,15} = {11,13}

Oh, let me put on my math hat and crunch some numbers for you.

First, let's find the intersection of sets A and B. So, (A �¾ B) would be {9, 10}.

Now, let's find the intersection of this new set with set C. So, ({9, 10} �¾ C) would be an empty set because it doesn't have any common members with set C.

Therefore, the members of the given set (A �¾ B) �¿ C are none at all! It's like a ghost town, empty and lonely.

To find the members of the set (A �¾ B) �¿ C, we need to follow a few steps:

Step 1: Find the union of sets A and B.
The union of two sets, denoted by A ∪ B, is the set that contains all the elements from both sets without any repetition. In this case, A = {9, 10, 11, 12} and B = {9, 10, 13, 14}. The union of A and B would be {9, 10, 11, 12, 13, 14}.

Step 2: Find the intersection of the result from Step 1 and set C.
The intersection of two sets, denoted by A ∩ B, is the set that contains all the elements that are common to both sets. In this case, the result from Step 1 is {9, 10, 11, 12, 13, 14}, and C = {11, 13, 15}. The intersection of these two sets would be {11, 13}.

Therefore, the members of the set (A �¾ B) �¿ C are {11, 13}.
