Answer:

$\frac{2}{11}$

Step-by-step explanation:

First, find the probability of him pulling out a book.

There are 11 objects in total, and there are 4 books.

So, the probability of pulling out a book is $\frac{4}{11}$

Next, find the probability of him pulling out a DVD after.

Since a book was taken out, there are only 10 objects left. There are 5 DVDs.

So, the probability of pulling out a DVD is $\frac{5}{10}$ , or simplified to $\frac{1}{2}$

To find the probability that this happens in order, multiply the probabilities:

$\frac{4}{11}$ x $\frac{1}{2}$

= $\frac{2}{11}$

So, the probability is $\frac{2}{11}$

Mrac [35]

Answer:

D) She has a total of $62 in the piggy bank.

Step-by-step explanation:

Jenny has been saving quarters in a piggy bank since she was born.

She decides to add 56 more quarters so that she can buy a $65 phone.

So she has 192 + 56 = 248 quarters currently.

1 quarter is equivalent to $0.25

248 quarters equals;

$\frac{248}{1}$ × $0.25 = $62

So Jenny has a total of $62 in the piggy bank.
