Objectives
Use the language of probability when
interpreting the results of an experiment
Know that if the probability of an event
occurring is p, then the probability of it
not happening is 1 – p
Know that the sum of probabilities of
all mutually exclusive outcomes is 1
and use this when solving problems
Identify all the mutually exclusive
outcomes of an experiment
1
Find and record all possible outcomes for
two or more successive events in a
systematic way, using tree diagrams
3–4
Estimate probabilities from experimental
data
5
3.4 Estimating
probability
Estimate probabilities for experimental data
Compare the likelihood of events
Understand that if an experiment is
repeated there may be, and usually will
be, different outcomes
Increasing the number of times an
experiment is repeated generally leads to
better estimates of probability
Appreciate that random processes are
unpredictable
Compare experimental and theoretical
probabilities in a range of contexts
Appreciate the difference between
mathematical explanation and
experimental evidence

3.5 Better
estimates of
probability
Understand that if an experiment is repeated there may be, and usually
will be, different outcomes
Increasing the number of times an experiment is repeated generally
leads to better estimates of probability
Appreciate that random processes are unpredictable
