Question

If A = {x / x ∈W, x < 10}, B = {x/x is a factor of 10}, C = { } 2 2 2 2 1 2, 3, ,....., 10 , then Find i) A ∪B ii) A ∩ B iii) A – C iv) B – C

Answer 1

Given

A = {x / x ∈W, x < 10},

B = {x/x is a factor of 10},

C={1,2,3...10}

Roster form of set A

A={0,1,2,3,4,5,6,7,8,9}

Roster form of set B

B={1,2,5,10}

A UB={0,1,2,3,4,5,6,7,8,9}U{1,2,5,10}

A UB={0,1,2,3,4,5,6,7,8,9,10}

A ∩ B={0,1,2,3,4,5,6,7,8,9}∩{1,2,5,10}

A ∩ B={1,2,5}

A – C={0,1,2,3,4,5,6,7,8,9}–{1,2,3,4,5,6,7,8,9,10}

A – C={0}

B – C={1,2,5,10}–{1,2,3,4,5,6,7,8,9,10}

B – C={empty set}
