Welcome to the probability theory and statistics page page.
Having the ability to accurately work out percentages and probabilities is an key Math skill to have.
Buying an item in a store sale, taking out a loan or opening a savings account are just a few examples of situations where a percentage of an amount will be involved.
Percentages crop up very often in our everyday life.
Percentages is a concept that also plays a big role in probability theory and representing probabilities.
Often when the probability of an specific event has been worked out, this probability value will then be written as a percentage. Where the higher the value of the percentage up to 100, the more probable the event is to occur.
Types of events in probability can have different definitions at times also, depending if the events are independent or dependent.
These concepts are covered further in more detail in the pages below, and shown in action with some detailed and structured examples.
Also introduced is the fundamental counting principle, which is a process that can be used to establish how many outcomes of an event or series of events could be possible to happen.
Making use of the fundamental counting principle is often the first step in approaching a question that involves working out probability.
