The total number of sample space in this item is calculated by adding up all the number of students given. That is,
   S = 600 + 400 + 300 + 200 = 1500
The probability is calculated with the equation below.
    P = n / S
where P is the probability,
          n is the number of sophomores, and 
          S is the total number of students
Substituting,
    
  P = 400 / 1500 = 4/15
<em>ANSWER: 4/15</em>
        
             
        
        
        
ANSWER
B. 3 ft by 8 ft
EXPLANATION
The area is given as 24 square feet.
This implies that,

The perimeter of the rectangular field is given as 22 feet.
This implies that,

Or

We make w the subject in this last equation and put it inside the first equation.

When we substitute into the first equation we get;


This implies that,



When l=3, w=24
Therefore the dimension is 3 ft by 8 ft
