Question

Set A,B and C are: A = {1, 2, 5,7,8,9,12,15,17}, B = { 1,2, 3 ,4, 5,9,10 } and C { 2, 5,7,9,10,11, 13}. Find A∩BUC , AUBUC, AUB∩C and (B~C)

Answer 1

Answer:

solved

Step-by-step explanation:

A = {1, 2, 5,7,8,9,12,15,17}

B = { 1,2, 3 ,4, 5,9,10 }  

C =  { 2, 5,7,9,10,11, 13}

A∩BUC =  { 1, 2, 5,7,9,10,11, 13 }

AUB∩C =  {1, 2 ,4, 5,7,8,9, 10 }

(B~C) = B - C = {1, 3 ,4  }
