Answer: Our required probability is 
Step-by-step explanation:
Since we have given that
Number of cards in a deck = 52
Number of nines = 4
Number of hearts = 13
It is the case of replacement.
Probability of drawing a nine the first time and a hear the second time is given by

Hence, our required probability is 
The true statement is that: if you cannot get from one term to the next by adding or multiplying by a constant value, the sequence is neither arithmetic nor geometric
<h3>How to determine the true statement</h3>
A progression can either be arithmetic, geometric or neither.
- When the progression has a common difference (gotten by addition), then the progression is arithmetic
- When the progression has a common ratio (gotten by multiplication), then the progression is geometric
If the above are not true, then the sequence is neither arithmetic nor geometric
