What the work shows

The task

Three bucketsThe teacher presented the students with the buckets as shown in the diagrams. She asked the students to give the probability, for each bucket, of selecting a red ball if they took one ball.

Frances's work shows that she is able to:

  • determine the theoretical probabilities of the outcomes of simple events
  • express the probabilities numerically.
