Help!!! U = {a, b, c, d, e, f, g, h}. A = {a, b, c, d, e}. B = {c, d, e, f}.?U = {a, b, c, d, e, f, g, h}.?

Help!!! U = {a, b, c, d, e, f, g, h}. A = {a, b, c, d, e}. B = {c, d, e, f}.?


U = {a, b, c, d, e, f, g, h}. A = {a, b, c, d, e}. B = {c, d, e, f}.


Which of the following is (A intersect B)C








Pick one:





{a,h,b}


{f,g,h}


{a,b,f}


{a,b,f,g,h}

Help!!! U = {a, b, c, d, e, f, g, h}. A = {a, b, c, d, e}. B = {c, d, e, f}.?U = {a, b, c, d, e, f, g, h}.?
If C is complement (') then the ans is {a,b,f,g,h}
Reply:A intersect B is none of the above. As for U??? and you didn't define C????





But do you learn anything by asking strangers - go to your textbook and look up sets and subsets
Reply:A intersect B = {d,e} since they have those in common


Then ( A intersect B) c = all the elements in U except d and e





={a,b,c,f,g,h}
