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
, or simplified to 
To find the probability that this happens in order, multiply the probabilities:
 x
 x 
= 
So, the probability is 
 
        
             
        
        
        
Answer:
Remainder is 691.
Step-by-step explanation:
Given function is  .
.
Now we need to find remainder if we divide given function  by (x-3)
 by (x-3)
(x-3) means plug x=3 into  to find remainder.
 to find remainder.
 







Hence remainder is 691.
 
        
                    
             
        
        
        
Answer 
Find out the  m∠6  .
To prove
As given
 a∥e , m∥n , and m∠2 = 112°.
As  m∥n 
a is the transversal (A line that cuts across two or more (usually parallel) lines is called transverasl.)
Thus
∠ 2 = ∠3 ( Corresponding angle property )
∠3 = 112°
Also 
 a∥e and m is transversal .
∠ 3 = ∠6 = 112 ° ( Corresponding angle property )
Therefore 
∠6 = 112°
