Now think of the following sets, C = {1,3,5,73
D = 2, 3, 5, 7)
Are C and D equal sets ? Obviously No
Because IEC,1 € D, 2 E D2 €
.. C and D are not equal sets. It is written as CD
If A = {1,2,3) and B = {1, 2, 3, 4; then A+B verify it.
A = {x|x is prime number and 10<x<20) and B = {11, 13, 17,19
Here A = B. Verify,
Practice set 1.2
Ex (3)
Ex (4)
(1) Decide which of the following are equal sels and which are not ? Justify yours
A= {x|3x -1 =2)
B = {xx is a natural number but x is neither prime nor composite
C = {
xXEN, x<2}
(2) Decide whether set A and B are equal sets. Give reason for your answer
A=Even prime numbers
B = {xl 7x -1 = 13}
(3) Which of the following are empty sets ? why?
(i) A= {ala is a natural number smaller than zero.}
(ii) B = {x|x = 0) (iii) C= {x5x - 2 = 0, XEN
