I don't see any following options to answer your questions.
 
        
             
        
        
        
Probability that the 7th grader is a boy = number of boys/(total kids) = 4/(4+4) = 1/2
  
Probability that the 8th grader is a boy = 5/(5+7) = 5/12
  
Probability that both are boys = 1/2*(5/12) = 5/24 or 20.8%
I hope this helps!
 
        
             
        
        
        
Probably not but no one really knows 1000% because there isn't any evidence to back it up
        
             
        
        
        
I personally always include:
Why You want the job
Skill lists. You never want to be a one trick pony.
Bloat about your knowledge to the job to which you're applying.
Your educational accomplishments.
And include little about yourself,( not too much bcz, the employer really wont care. they just want someone ready to do the job.)
 
        
             
        
        
        
The answer is C. Hope it helps! :)
