Answer 1

Answer:

What is the cardinality of the set of odd positive integers less than 10? Explanation: Set S of odd positive an odd integer less than 10 is {1, 3, 5, 7, 9}. Then, Cardinality of set S = |S| which is 5.

Answer 2

SOLUTION

TO DETERMINE

The cardinality of the set of odd positive integers less than 10

CONCEPT TO BE IMPLEMENTED

SET :

A set is a well defined collection of distinct objects of our perception or of our thought to be conceived as a whole

Representation of Set :

A set can be represented in following ways

(i) Statement form method

(ii) Roster or tabular form method

(iii) Rule or set builder form method

EVALUATION

Here the given set is Set of odd positive integers less than 10

Let A be the set

Then A = Set of odd positive integers less than 10

Now the odd positive integers less than 10 are 1 , 3 , 5 , 7 , 9

Thus A = { 1 , 3 , 5 , 7 , 9 }

Thus the cardinality of the Set A

= The number of elements in A

= 5

FINAL ANSWER

The cardinality of the set of odd positive integers less than 10 = 5
