Study Notes
Probability Basics
- The range of the probability of an event is between 0 and 1.
Interpretation of Probability Values
- A probability of 0.5 indicates an equal likelihood of an event occurring or not occurring (50% chance).
- A probability of 1 indicates an event with certainty (will definitely occur).
- A probability of 0 indicates an impossible event (will definitely not occur).
Branch of Mathematics
- The branch of mathematics that deals with numerical descriptions of how likely an event is to occur is probability theory.
