Answer:
(a)
(b)
(c)
Step-by-step explanation:
Number of juniors who attended prom,n(J)=28
Number of seniors who attended prom,n(S)=97
- Total of those who attended prom=125
Number of juniors who did not attend prom,n(J')=56
Number of seniors who did not attend prom,n(S')=19
- Total of those who attended prom=75
- Total Number of students=200
(a) P (a junior who did not attend prom)

(b)


(c)P (junior | attended prom)


 
        
                    
             
        
        
        
Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0. 
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0 
                              x = [ -b ± √(b^2 - 4ac) ] / (2a) 
                              x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) ) 
                              x = [-5 ± √(25 - (-40) ) ] / ( -4 ) 
                              x = [-5 ± √(65) ] / ( -4) 
                              x = [-5 ± sqrt(65) ] / ( -4 ) 
                              x = 5/4 ± -sqrt(65)/4 
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
