Question

A = { 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 }, B = {0, 4, 8, 12, 16, 20, 24, 28, 32} and C = {0, 5, 10, 15, 20, 25, 30, 35 }, then find

i). A∪B ii). A∪C iii). B∪C iv). A∩B v). A∩C

Answer 1

Answer:

i ) AUB

A = { 3,6,9,12,15,18,21,24,27,30 }

B = {0, 4, 8, 12, 16, 20, 24, 28, 32}

AUB = { 0,3,4,6,8,9,12,15,16,18,20,21,24,27,28,30,32 }

ii ) AUC

A = { 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 }

C = {0, 5, 10, 15, 20, 25, 30, 35 }

AUC = { 0,3,5,6,9,10,12,15,18,20,21,24,25,27,30,35 }

iii) BUC

B = {0, 4, 8, 12, 16, 20, 24, 28, 32}

C = {0, 5, 10, 15, 20, 25, 30, 35 }

BUC = { 0,4,5,8,10,12,15,16,20,24,25,28,30,32,35 }

iv) AnB

A = { 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 }

B = {0, 4, 8, 12, 16, 20, 24, 28, 32}

AnB = { 12 , 24 }

v) AnC

A = { 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 }

C = {0, 5, 10, 15, 20, 25, 30, 35 }

AnC = { 15 , 30 }

AUB : All the elements belongs to A and B.

AnB : Common elements in both A and B .

Answer 2

Answer:

i). A∪B is the correct answer

Step-by-step explanation:

A = { 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 }, B = {0, 4, 8, 12, 16, 20, 24, 28, 32} and C = {0, 5, 10, 15, 20, 25, 30, 35 }, then find
