Answer:
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 
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 
, or simplified to 
To find the probability that this happens in order, multiply the probabilities:
x
=
So, the probability is

Answer:
Rotation:
Step-by-step explanation:
Translation is usually movements like up, down, left, right.
Dilation is when one shape is bigger/smaller than the other, but still congruent.
Reflections are usually done over an axis (x or y), and don't change the degree at which a shape is turned. From looking at the triangles, you can see that one triangle was turned clockwise.

15 rides because I had gotten this correct on my test
Answer:
The experimental probability is the same as the theoretical probability.
Step-by-step explanation:
Theoretical probability of a yellow tile 1/5
1/5 * 50 trials = 10 yellow tiles should be drawn
