Let A be the set of prime number smaller than 6 and B be the set of prime factors of 30. Check if A and B are equal.

Write the following sets in the roster form. (i) B is the set of all months in a year having 30 days. (ii) P is the set of all prime numbers smaller than 10. (iii) X is the set of colours of the rainbow.

A is the set of prime number less than 10, B is the set of odd numbers less than 10 and C is the set of even numbers of less than 10. Which of the following statements are true? (i) A subset B (ii) B subset A (iii) A subset C (iv) C subset A (v) B subset C (vi) phi subset A

State whether the followmg sets are finite or infinite. (i) The set of months in a year. (ii) {1,2,3, ..., 99, 100) (iii) The set of prime numbers smaller than 99. (iv) The set of letters in the English alphabet. (v) The set of lines that can be drawn are parallel to the X-Axis (vi) The set of numbers which are muitiplies of 5. (vii) The set of circles passing through the origin (0,0).
