For a=(al, beth, carl, evan) and b-(beth, dan, evan, fred), list all elements in aub, a n b anda- b.

1) A∪B = {Al, Beth, Carl, Evan, Dan, Fred}

2) A∩B= {Beth, Evan}

3) A - B = only A = { Al, Carl}

Step-by-step explanation:

Since we have given that

A={Al, Beth, Carl, Evan}

B = {Beth, Dan, Evan , Fred}

We need to find A∪B, A∩B and A - B .

Since A∪B is the set of union i.e. collection of all sets A and B.

So, A∪B = {Al, Beth, Carl, Evan, Dan, Fred}

A∩B is the set of intersection i.e. the common element in both the sets A and B.

A∩B= {Beth, Evan}

And A - B is the set containing only A but not B.

A - B = only A = { Al, Carl}
