• A two-way table is a way of organising data that shows the frequency of combinations of two categorical variables.
• The sum of all frequencies in a two-way table equals the total number of outcomes or trials.
• When all elementary outcomes are equally likely, `P(A)` equals the number of favourable outcomes divided by the total number of possible outcomes.
• Experimental probability is calculated using data collected from an experiment, not theoretical assumptions.
• The expected number of times an outcome will occur is found by multiplying the probability of the outcome by the total number of trials.
• A sample space diagram lists all possible outcomes of one or more events.
• For two independent events, the total number of possible outcomes is the product of the number of outcomes for each event.
• Probabilities from a sample space diagram can be found by counting the number of favourable outcomes and dividing by the total number of possible outcomes.
• Probabilities are always between 0 and 1, inclusive.
• The sum of probabilities for all possible outcomes in a sample space is 1.

• Complete a two-way table given partial data, including filling in missing totals and frequencies.
• Use data from a two-way table to calculate probabilities of single events and combined events.
• Record data accurately from a simple experiment, such as coin tosses, dice rolls, or drawing coloured counters.
• Interpret data from a simple experiment to describe observed frequencies and patterns.
• Estimate the probability of an event based on experimental data.
• Use estimated probabilities to calculate the expected number of times an outcome will occur in a given number of trials.
• List all possible outcomes for two events using a sample space diagram.
• Find and interpret probabilities of specific outcomes or combinations of outcomes using a sample space diagram.
