Sections

  1. 5A Describing probability Mastered

    The language of chance (impossible, unlikely, even chance, likely, certain) and the probability scale from 0 to 1.

  2. 5B Theoretical probability Mastered

    Sample spaces, equally likely outcomes, calculating theoretical probability, and the probability of an event not happening (the complement).

  3. 5C Experimental probability Mastered

    Relative frequency from experiments and surveys, using it to estimate probability, and expected numbers of outcomes.

  4. 5D Compound events, Venn diagrams and two-way tables Mastered

    Events using and, or and not, mutually exclusive events, and organising outcomes in Venn diagrams and two-way tables to find probabilities.
