What students should be able to do by the end of this unit.

Probability Basics

0 / 3 ticked

Tick to track on this device. Saved here only — your teacher does not see it.

  • Understand experimental and theoretical probability and express results as fractions, decimals or percentages.
  • Use compound events with tree diagrams (with and without replacement) and two-way tables.
  • Calculate the probability of unions using $P(A \cup B) = P(A) + P(B) - P(A \cap B)$.

Conditional Probability and Independence

0 / 5 ticked

Tick to track on this device. Saved here only — your teacher does not see it.

  • Understand and calculate conditional probability using $P(B \mid A) = \dfrac{P(A \cap B)}{P(A)}$.
  • Identify and test for mutually exclusive events ($P(A \cap B) = 0$).
  • Identify and test for independent events ($P(A \cap B) = P(A) \cdot P(B)$).
  • Solve problems combining Venn diagrams, tree diagrams and conditional probability.
  • Understand factorial notation, permutations and combinations.ENR
