Curriculum for Probability:Years 7 to 9Pupils should be taught to record, describe and analyse the frequency of outcomes of simple probability experiments involving randomness, fairness, equally and unequally likely outcomes, using appropriate language and the 0-1 probability scale more... Pupils should be taught to understand that the probabilities of all possible outcomes sum to 1 more... Pupils should be taught to generate theoretical sample spaces for single and combined events with equally likely, mutually exclusive outcomes and use these to calculate theoretical probabilities more... Years 10 and 11Pupils should be taught to apply the property that the probabilities of an exhaustive set of mutually exclusive events sum to 1 more... Pupils should be taught to use a probability model to predict the outcomes of future experiments; understand that empirical unbiased samples tend towards theoretical probability distributions, with increasing sample size more... Pupils should be taught to calculate the probability of independent and dependent combined events, including using tree diagrams and other representations, and know the underlying assumptions more... Pupils should be taught to {calculate and interpret conditional probabilities through representation using expected frequencies with two-way tables, tree diagrams and Venn diagrams} more... Years 12 and 13Pupils should be taught to understand and use mutually exclusive and independent events when calculating probabilities. Link to discrete and continuous distributions more... Pupils should be taught to understand and use simple, discrete probability distributions (calculation of mean and variance of discrete random variables is excluded), including the binomial distribution, as a model; calculate probabilities using the binomial distribution more... Pupils should be taught to understand and use conditional probability, including the use of tree diagrams, Venn diagrams, two-way tables. Understand and use the conditional probability formula P(A|B)=P(A∩B)/P(B) more... Pupils should be taught to understand and use the Normal distribution as a model; find probabilities using the Normal distribution. Link to histograms, mean, standard deviation, points of inflection and the binomial distribution more... Pupils should be taught to conduct a statistical hypothesis test for the proportion in the binomial distribution and interpret the results in context. Understand that a sample is being used to make an inference about the population and appreciate that the significance level is the probability of incorrectly rejecting the null hypothesis more... Pupils should be taught to modelling with probability, including critiquing assumptions made and the likely effect of more realistic assumptions more... Pupils should be taught to select an appropriate probability distribution for a context, with appropriate reasoning, including recognising when the binomial or Normal model may not be appropriate more... Pupils should be taught to conduct a statistical hypothesis test for the mean of a Normal distribution with known, given or assumed variance and interpret the results in context more...

Notes:Probability is a measure of the weight of evidence, and is arrived at through reasoning and inference. In simple terms it is a measure or estimation of likelihood of the occurrence of an event. The word probability comes from the Latin word probabilitas which is a measure of the authority of a witness in a legal case. Some of the earlier mathematical studies of probability were motivated by the desire to be more profitable when gambling. Today however the practical uses of probability theory go far beyond gambling and are used in many aspects of modern life.
Probability Teacher Resources:Dice and Spinners: Computer generated random numbers for games and probability experiments Probability Words: A visual aid to highlight the vocabulary of probability and to debate the relationship between the given words.

Compare your opinion with thousands of others. Probability: Basic probability questions in an online exercise. Hi-Low Predictions: A version of the Play Your Cards Right TV show. Calculate the probabilities of cards being higher or lower. Remainder Race: A game involving chance and choice requiring an ability to calculate the remainder when a two digit number is divided by a single digit number.

Pascal's Triangle: Get to know this famous number pattern with some revealing learning activities Tree Diagrams: Calculate the probability of independent and dependent combined events using tree diagrams. The Maths of Gambling: Gambling is never a good idea and this activity might help you understand the mathematics involved. Conditional Probability: Find the probability of one event happening given that another event has already happened. Probability Formulae: Show that you know which formula (as given in the IB Formula Booklet) to use for each probability question. A drag and drop challenge. Finally there is Topic Test, a set of 10 randomly chosen, multiple choice questions suggested by people from around the world.

Can you think why this is true? Probability Videos:Probability Video: A reminder of how to work out basic probability leading to simple combined events and expected values. Calculator Dice Video: If you have no dice don't despair because most scientific calculators have a random number generating facility as can be seen in this short video. Tree Diagrams Video: Tree diagrams can be really helpful showing combinations of two or more events in order to calculate probabilities.
