A = {1, 3, 7, 9, 10} B = {2, 5, 7, 8, 9, 10}, find A ∩ B

A ∩ B = {7, 9, 10}

A = {2, 3, 4, 5}, B ={c, d, e, f} and C = {4, 5, 6, 7}, find (A ∪ B) ∩ (A ∪ C)

(A ∪ B) ∩ (A ∪ C) = {2, 3, 4, 5}

C = {0, 1, 3} and B = {2, 5, 7, 8, 9, 10}, find B ∩ C

B ∩ C = { }

A = {2, 3, 4, 5}, B ={c, d, e, f} and C = {4, 5, 6, 7}, find A ∪ (B ∩ C)

A ∪ (B ∩ C) = {2, 3,4, 5, c, d, e, f}

set P is the set of numbers less than 5. Set T is the set of numbers between 1 and 6

P∩𝑇={2, 3, 4}

X={a,c,e,g,i}, Y={b,c,e,f}, and Z={b,d,f}, find Z ∩ (X ∪ Y)

Z ∩ (X ∪ Y) = {b, f}

A = {2, 4, 6, 8, 10, 12}, set B = {3, 6, 9, 12, 15} and set C = {1, 4, 7, 10, 13, 16}, find A ∪ B

A ∪ B = {2, 3, 4, 6, 8, 9, 10, 12, 15}

X={a,c,e,g,i}, Y={b,c,e,f}, and Z={b,d,f}, find Y ∪ (Z ∩ X)

Y ∪ (Z ∩ X) = {b, c, e, f}
