Week 3
• Conditional Probability
• Independent Events
• Bernoulli Trials
• Binomial Distribution

Learning Outcomes
The learning outcomes will be aligned with the learning outcomes of the LC Higher Maths Syllabus listed here:

• Decide whether an everyday event is likely or unlikely to occur
• Recognise that probability is a measure on a scale of 0-1 of how likely an event is to occur
• Use the language of probability to discuss events, including those with equally likely outcomes
• Estimate probabilities from experimental data
• Recognise that, if an experiment is repeated, there will be different outcomes and that increasing the number of times an experiment is repeated generally leads to a better estimated probability
• Associate the probability of an event with its long-run, relative frequency
