Answer:
Is that all to the problem?
Step-by-step explanation:
 
        
                    
             
        
        
        
5x + 7 ≤ −8                        or                     3x + 7 > 19
5x  ≤ - 15                            or                          3x > 12
  x ≤ - 3                              or                             x > 4
Answer
  x ≤ - 3    or   x > 4
 
        
             
        
        
        
P(not 5) =5/6 and P(5) = 1/6
If the first 5 is rolled on the 5th roll then the first four rolls were not 5
P(5 on fifth roll) = 5/6 x 5/6 x 5/6 x 5/6 x 1/6 = 5^4/6^5 = 625/7776 = 0.080375...
