conversations.value: If the class has 300 students, there are 40/100*300 = 120 smoking students.
  In a year, 70% of the smoking students are hospitalized from smoking-related complications, a total of 70/100*120 = 84 students.
  The number of smoking students who've not been hospitalized from smoking-related complications is 120-84 = 36
