Question

What is the cardinality of the set of odd positive integers less than 10?

Answer 1

Step-by-step 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

$\large\underline\pink{ \underline { \sf \maltese{ \: Answer:- }}}$

• The cardinality is nothing but the set of a measure of the " number of elements " of the set.
• The odd positive numbers less than 10 are { 1, 3, 5, 7, 9 }
• Let the cardinality set be H, There are 5 elements in set H; therefore, the cardinality of set H is 5.

$( \: 1, 2, 3, 4, 5 \: ) \: then, \: the \: \\ cardinality \: of \: set \: H \: \\= |H| \: which \: is \: 5$
