Answer:
See explanation below. 

Step-by-step explanation:
Notation
First we need to define the following events:
E = The student is in a major of enginnering
O= The student is in a major different from enfinnering
M= The student is in the marching band
Solution for the problem
For this case we can calculate the following probability:

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability  the student is in the marching band"
And the probability that need to calculate to compare is this one:

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability  the student is in the marching band"
And if the claim is satisfied we need to see this:

 
        
             
        
        
        
The answer to your question is b
        
             
        
        
        
Answer:
x=6
Step-by-step explanation:
 Remember, the formula for area is the length times the width. So, if we know the width is 3, and we know the total area is 24, all we need to do is divide 24 by 3 to get 8. 8 is the split up side, the one that is x + 2. To find x, simply subtract 2 from 8. 8 - 2=6.
24/3=8
8-2=6
