Frequency and outcomes (AQA GCSE Maths): Flashcards

Possible results that could happen in probability problems

How often each outcome occurs in a data set

Diagram using branches to show frequencies of outcomes for multiple events

Each frequency equals the sum of its branches

Shows all possible outcomes when two events happen together

Usually displayed as a table or grid

Four possible outcomes: HH, HT, TH, TT

Always equals 1

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