Answer 1

This is a simple and neat idea, I am a electromechanical engineer and I am just learning JS. This is going to print a random numeber between 1 and 100. Except 8 and 15

 var r;   // this is the random integer.
 var val; //this will serve as validator for the random integer.

 val=0; 
 while(val==0)    {
 r=Math.round(Math.random()*100)+1;
 if(r!=8 && r!=15){val=1;}    //a valid number will be any number different from 8 and 15
                              //then validator will change and go out from the loop.
                }   
document.write(r);
