Probability
Probability is a skill on Pengi from Lesson 32: Probability in Saxon Math, Course 3.
Key Concepts
Property Probability is the likelihood that a particular event will occur. We express probability as a number ranging from zero to one. $$P(\text{Event}) = \frac{\text{number of favorable outcomes}}{\text{number of possible outcomes}}$$.
Examples Rolling an even number on a 6 sided die, the probability is: $P(\text{even}) = \frac{3}{6} = \frac{1}{2}$ Picking a blue marble from a bag with 5 red and 3 blue ones: $P(\text{blue}) = \frac{3}{8}$.
Explanation Think of probability as a score for how likely something is, from 0 (no way!) to 1 (for sure!). It’s a fraction comparing what you want to happen to everything that could happen. This helps you predict outcomes in games or experiments!
