## anonymous one year ago Given the following sets. A = {0, 1, 2, 3} B = {a, b, c, d} C = {0, a, 2, b} Find B C {0, 1, 2, 3} {a, b, c, d} {0, a, 2, b} empty set {a, b, c, d, 0, 2}

you want BUC

3. anonymous

I believe you combine the two lines... So you have ABCD and 0A2b Combining it would become ABCD02...

if it is union ,write all the elements of both the sets but only once.
