About probability notes
GoConqr OriginalWhat these probability notes cover
The notes take several approaches to the unit. One introduces outcomes and sample spaces, while another explains independent and dependent events. Compound events looks at events made up of two or more simple events. Other notes cover set notation, Venn diagrams and conditional probability.
For an introduction, start with the note on probability as a measure of how likely an event is. It considers possible outcomes before moving on to finding probabilities. The sample-space notes are a next step if you want to focus on the vocabulary.
Revise with notes
Read a short section, then write down its key terms in your own words. Return to the relevant note when you need to check a definition or rule. When you are ready to test your recall, switch to flashcards or a quiz on the Probability unit page.
Pick a note and work through it at your own pace.
Frequently asked questions
Which note is a useful place to start?
The note that introduces probability as a measure of how likely an event is is a useful starting point. It discusses possible outcomes and introduces probability using numbers. You can then move to the notes on sample spaces for more vocabulary.
What topics do the notes cover?
The notes cover sample spaces, independent and dependent events, compound events, set notation and conditional probability. There is also a note called The Monty Hall Problem. You can choose a topic that matches what you are studying rather than reading the notes in order.
Are these notes free to use?
Yes. Every note listed on this page is free to open and study without an account. The resources were made by GoConqr users, not by GoConqr. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
