48 sets i believe since there are only 48 maximum of blue, green and yellow crayons therefore the 49th set would only contain a red crayons and a picture
        
                    
             
        
        
        
That's the simplest it can go. 
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Given
Let
 Undergraduates
 Undergraduates
 Graduates
 Graduates
So, we have:
 -- Total students
 -- Total students
 --- students to select
 --- students to select
Required

From the question, we understand that 2 undergraduates are to be selected; This means that 2 graduates are to be selected.
First, we calculate the total possible selection (using combination)

So, we have:





Using a calculator, we have:

The number of ways of selecting 2 from 3 undergraduates is:




The number of ways of selecting 2 from 5 graduates is:




So, the probability is:




 
        
             
        
        
        
Answer:
π
Step-by-step explanation:
 
        
                    
             
        
        
        
Since both C & D are parallel, angle 2 is a corresponding angle to the angle of 108 degrees, so angle 2 is also 108 degrees
