If U = {2, 4, 6, 8, 10, 12, 14} and A = {2, 6, 10}, what is the cardinality fo A'? а. 3 b. 6 С. 4 d. 7

Suppose u = (4,3,0), v = (-1, -5, 5) and = (5,-4, 0). Then: w u • v= u • w= v • w= v • v= ū. (v + w) =

{1,2, a, b, Ø}. Denote S2 = S1 \ {Ø}. Then S2 n S, C S . Let Sj = Select one: True False Let Sj = {1, b, {c}} and S2 = {b, {c},3}. Then SI U S2 = {1,b, {c},3}. Select one: True False Let JA| = 10, |B| = 10, and A n B + Ø. Then |A U B| = 20. %3D %3D Select one: O True O False

1. Use set identities to show that (A U B)n (BU A) = A where A and B are sets. Let A = {1,2, 3} and B = {{0}, {1}}. Find A × B. 2.
