Probability As A Measure Of Likelihood

Make Connections

Performance Task

Ways of Thinking: Make Connections

Take notes about how your responses compared to those of your classmates.


As your classmates present, ask questions such as:

  • What statement about likelihood could you make for each event? (For example: It is very unlikely that I would be chosen at random for a prize.)
  • How did you decide where to place a mark for each event?
  • What is the likelihood that both events, "You will be chosen at random to win a prize" and "You will not be chosen to win a prize," will happen?
  • How does the likelihood of the opposite of each event compare to the likelihood of the original event? (For example, “It will not rain tomorrow” versus “It will rain tomorrow” and “The temperature will be below 60°F” versus “The temperature will be above 60ºF”)?
