    What is probability?

    Probability measures how likely an event is, on a scale from 0 to 1, using favourable outcomes over total outcomes.

    Why it matters

    It supports statistics, risk reasoning and a reliable block of exam marks.

    Key concepts you will practise

    • Sample space and events
    • Probability of simple and compound events
    • Complementary events
    • Independent and mutually exclusive events

    Tips that save marks

    • List the sample space explicitly for small problems — it prevents miscounting.
    • P(not A) = 1 − P(A) is often the fastest route.

    Frequently asked questions

    What does a probability of 0 mean?

    The event is impossible; a probability of 1 means it is certain.

    What is the difference between mutually exclusive and independent events?

    Mutually exclusive events cannot both happen; independent events can, but one does not affect the other's chance.
