: Im having a hard tiume understanding how to list these sets
4. (7 pts) Given U = {All letters of the alphabet} A = {b, c, d} and B = {c, e, f, g}
List the elements of set
(a) A U B (b) A ∩ B (c) A′ ∩ B′ (d) A′ U B′ (e) A U B′
(f) (A U B′ ) ∩ B (g) (A U B) ∩ (A U B′)

You can put this solution on YOUR website! Given U = {All letters of the alphabet} A = {b, c, d} and B = {c, e, f, g}
A' = aefghijklmnopqrstuvwxyz ; B'=abdhijklmnopqustuvwxyz
------------------------------
List the elements of set
(a) A U B = bcdefg
(b) A ∩ B = b
(c) A′ ∩ B′= ahijklmnopqrstuvwxyz
(d) A′ U B′= abdefghijklmnopqustuvwxyz
(e) A U B′ = abcdhijklmnopqustuvwxyz
(f) (A U B′ ) ∩ B = {abcdhijklmnopqrstuvwxyz}intersect B = c
(g) (A U B) ∩ (A U B′) = {bcdefg}intersect{abcdhijklmnopqrstuvwxyz} = bcd
================================
Cheers,
