Mathematics — first biennium · Lesson
With equally likely outcomes, probability is favorable outcomes divided by possible outcomes. It must stay between 0 and 1.
Prerequisites: Fractions and sets
Goal: Build an equally likely sample space and calculate classical probability.
In this lesson: Build an equally likely sample space and calculate classical probability.
New concept: The sample space Ω contains all possible outcomes. An event E contains only the outcomes of interest; when outcomes are equally likely, P(E)=favourable outcomes/possible outcomes.
How to proceed: List the sample space {1,2,3,4,5,6} first; then count only outcomes satisfying the event.
You can already assume: Fractions and sets.

List the sample space {1,2,3,4,5,6} first; then count only outcomes satisfying the event.
Data / situation: Roll a fair six-sided die: an even number is rolled.
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
