Document Summary
Many ways to collect data, surveys, experiments, simulations etc. Number that represents the chance of an event occurring (always between 0 & 1) normally expressed as fraction or decimal. Sample space: list of possible outcomes from experiment. Random: when something is random, it means it is not influence by anything other than chance. List a range of numbers, (eg 1-30) mark all composite numbers, the multiples of each prime starting with 2, then 3, then next uncrossed number and keep going. Numbers we can multiply together to get a certain product.
