In this module, you will have the opportunity to explore some basic concepts about probability.

The motivating CAHSEE release question for this module is the following:

Mr. Gulati is holding five cards numbered 1 through 5. He has asked five students to each randomly pick a card to see who goes first in a game. Whoever picks the card numbered 5 goes first.

  • Deepen your understanding of mathematical concepts, including:
    • Developing understanding of probability; and
    • Comparing independent and dependent events.
  • Develop skills in new instructional strategies, including
    • Stepping into math concepts with careful transition from non-math to mathematical representations.
