Question

plz solve these 3 questions
q.12,13 and 14​

Answer 1

Sure I will answer it for you mate

A = (3,6,9,12,15,...)

B = (4,8,12,16,20,24,...)

A intersection B = (12,24,36,478,....)

A U B = (3,4,6,8,9,12,15,16,20,......)

13) A = (1,3,5 )

B = (2,4,6)

A U B = (1,2,3,4,5,6)

14) n(A) = 4 , n(B) = 5 , n(A intersection B)= 2

n(A U B) = 4+5-2 = 7
