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 prior 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).

Tick the set which is infinite (A) The set of whole numbers lt 10 (B) The set of prime numbers lt 10 (C) The set of integers lt 10 (D) The set of factors of 10

Consider the experiment of rolling a die. Let A be the event 'getting a prime number', B be the event 'getting an odd number'. Write the sets representing the events (i) A or B (ii) A and B (iii) A but not B (iv) 'not A.
