Probability & Basic Statistics
Probability scale, equally likely outcomes and averages in context.
Probability describes chance; statistics summarises data – both need careful language.
Probability
Scale 0 to 1. Equally likely outcomes: P = favourable ÷ total.
Averages
Mean, median, mode, range – when each is useful.
Misconceptions
Past results do not change independent fair trials.
P(rolling a 3 on a fair die)?
1/6.
Practice
1. P(impossible event)?
2. When is the median useful?
