Answer:
Elements of the set: 9,10,11,12,13,14,15
Cardinality of the set: 7
Step-by-step explanation:
Firstly the set describes that A contains the values of k which are positive integers only.
Secondly it limits the values of k to be between 8 and 16, exclusive of both upper and lower limits.
Therefore we list all positive integers between 8 and 16 i.e. 9,10,11,12,13,14,15
Finally, we count the numbers of elements in the set which is also known as cardinality of the set i.e. 7 for our given set.
