Probability Distribution

Activity: Simulation

0/5 marks
  • Set a population for the closed environment.1 mark
  • Uncheck all contagious sums and start the simulation.1 mark
  • Select one contagious sum, such as 7, and observe the number of infections.1 mark
  • Check pause with each contact to see how disease is transmitted.1 mark
  • Check more than one contagious sum, such as 7 and 8, to simulate higher contagiousness.1 mark
The simulation is ready. No contagious sums are selected.

Observations

Discuss Thinking Questions

Imagine there is an outbreak of a virus at your school. How likely is it that you will catch the virus?

What are some possible outcomes in each interaction between students, teachers and others in the closed environment?

3 possible outcomes in each interaction

  • Come into contact with an infected person but not infected.
  • Come into contact with an infected person and was infected.
  • Did not come into contact with an infected person.
