Answer:
The constant of proportionality is thus 1
Step-by-step explanation:
Note that the green line passes through (6, 6) and has a y-intercept of 0.  Thus, the equation of the line is y = (6/6)x + 0, or y = x, or y = 1x.
The constant of proportionality is thus 1, which is also the slope of this line.
 
        
             
        
        
        
Solution :
It is given that four different prizes were awarded. So, 
 a). 4 ways for person 47 to win a prize
      99 ways to give out the 2nd prize
      98 ways to give the 3rd prize
       97 ways to give the last prize
      ∴  P(99,3) = 99 x 98 x 97
b). 1 way to give person 47 their prize
     1 way to give person 19 their prize
     98 ways to give out the 3rd prize 
     97 ways to give out the last prize 
     So, P(98,2) = 98 x 97
