• ∅

if set A and Set B has no elements in common so set A and set B will be _______ set.

• disjoint

• joint

• universal

• reciprocal

given:

U = { 1, 2, 3, 4, 5}

A = { 1, 2, 3 }

what is the complement of set A?

• A' = { 1,2,3,4,5}

• A' = { 1,2,3,}

• A' = { 4,5}

• A' = { }

given:

A = { 1, 2, 3 }

B = { 1, 3, 4 }

what is the universal set?

• U = { 1,2,3,4,5}

• U = { 1,2,3,4}

• U = { 1,2,2,4,}

• U = { 1234}

Given:

U = { 1, 2, 3, 4, 5}

A = { 1, 2, 3 }

B = { 1, 3, 4 }

What is the (AUB)' ?

• ( A U B )’ = {1,2,3,4}

• ( A U B )’ = {1,2}

• ( A U B )’ = {3,4}

• ( A U B )’ = {5}

U={ Jin, Suga, J-Hope, NamJoon, Jimin, TaeHyung, Jungkook}

A={ Jin, Suga, J-Hope}

B= {NamJoon, Jimin, TaeHyung}

C= {TaeHyung, Jungkook}

What is the complement of set B?

• B'={NamJoon, Jimin, TaeHyung}

• B'={NamJoon}

• B'= { Jin, Suga, J-Hope}

• B'= { Suga, J-Hope}
