Question 13 Marks

Given:
A = {Natural numbers less than 10}
B = {Letters of the word ‘PUPPET’}
C = {Squares of first four whole numbers}
D = {Odd numbers divisible by 2}.
Find: n(A ∪ D)

Answer

Here,
A= {1, 2, 3, 4, 5, 6, 7, 8, 9}
B = {P, U, E, T}
C = {0, 1, 4, 9}
D = { } or Φ
A ∪ D = {1, 2, 3, 4, 5, 6, 7, 8, 9}
n(A ∪ D) = 9
