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}
