Answer:
4845 ways
Step-by-step explanation:
To solve this problem we use the formula of combinations

Where n is the total number of students that can be chosen and you choose r from them.
So

Note that in this case the order in which the 4 students are chosen does not matter.
Then


 
        
                    
             
        
        
        
I believe C/12=pi which means the answer would be B.
