Assign Probabilities

The Assigning Probabilities handout shows a likelihood line that is similar to the one you used in the last lesson.

  • How should the marks for Imposssible, Certain, and Equally Likely as Unlikely be labeled?
  • On the likelihood line, assign a probability from 0 to 1 for these events. Mark each of these events on the line.
    • It will rain tomorrow.
    • You will send a text sometime today.
    • Out of all the students at your school, you will be chosen at random to win a prize.
