I would say none 
because each one equals to 24 students, when it says there are 24 students in each are class. so you would need to do 24 * 5 to get the amount of students.
 
        
                    
             
        
        
        
The set of all possibilities is called sample space and is denoted by S.
So, S = {NBD, NDB, BDN, BND, DBN, DNB} and n(S) = 8
and we need to find the probability of NBD
E = {NBD} and n(E) = 1
The probability of an even is defined by p(E) = 
Hence,  p(E) = 
 
        
             
        
        
        
Hello : 
P(x) + P(x') =1   ...( x' is the <span>complement of x)
0.3 +</span> P(x') =1
 P(x') = 1 - 0.3 = 0.7
        
             
        
        
        
Answer:
C. 176.6 Square feet (I think)
Step-by-step explanation:
I tried many different ways and got three of the answers above but I think this is the right one. 
The equation to find area of a circular cone base: 
- We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula:  
- Plug in numbers:  ≈ ≈ 
- Use the Area formula now that you have radius:  
- Solve and get =  
- Looking at the options the closest one to our answer (off by one-tenth) is C.
Sorry if you get this wrong. I tried lol.
