Probability 2 (AQA GCSE Maths): Flashcards

1

Probability that an event won't happen

$P( ext{not}) = 1 - P( ext{event})$

Set up equation: all probabilities sum to 1

How many times an event is expected to occur over many trials

Number of trials × probability

All outcomes equally likely

Some outcomes more likely than others

1 - rac{1}{6} = rac{5}{6}

Results differ greatly from expected values
