ou draw one card from a 52-card deck. Then the card is replaced in the deck and the deck is shuffled, and you draw again. Find

julsineya [31]

Answer: Our required probability is $\dfrac{1}{52}$

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

$\dfrac{4}{52}\times \dfrac{13}{52}\\\\=\dfrac{1}{13}\times \dfrac{1}{4}\\\\=\dfrac{1}{52}$

Hence, our required probability is $\dfrac{1}{52}$

Select from the drop-down menu to correctly complete the statement.

Usimov [2.4K]

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
