Question

Question 2 State which of the following sets are finite, infinite or null: (1 mark each) a) {1,3,5,7,9, ... ... ... . } = b){3,6,9,12} = c) {odd numbers which can be divided exactly by 2}=​

Answer 1

a) Infinite. b) finite. c) null

Explanation:

a) This set is an Infinite set since the list of elements of the set continue to grow and never end as depicted by the dots, thus making it neverending.

b) This set is finite due to the fact that all elements are included inside the curly brackets.

c) This is a null set, or an empty set, because the set has no elements due to the fact that there are no odd numbers that are divisible by 2.
