WebIn order to calculate n[ A ∪ ( B ∩ C ) ], let us use this known A ∪ B formula. n(A ∪ B)= n(A) + n(B)- n(A ∩ B) n[ A ∪ ( B ∩ C ) ] =n(A) + n( B ∩ C ) - n(A ∩ ( B ∩ C)) = 8+ 24 -21 =11. n[ A ∪ ( B ∩ C ) ] =11. Given the following venn diagram, find n[ A ∪ ( B ∩ C ) ]. Webb) Given that set A ={ }1,2,3,4 , B =[ 3,4,5,6,7 ]and C ={6,7,8,9} Find: i. A∆B (3 marks) ii.
