Key Concepts:
- Definition of Probability: Probability measures the likelihood of an event occurring and is expressed as a fraction, decimal, or percentage.
- Basic Probability Formula: The probability of an event occurring is calculated as: (P(A) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}})
- Understanding Random Selection: Every outcome has an equal chance of being selected when choosing randomly.
Skills Covered:
- Computing simple probabilities from a given dataset.
- Expressing probability in different formats (fractions, decimals).
Example Problems:
- A bag contains 4 red and 6 blue balls. What is the probability of randomly drawing a red ball?
- If a six-sided die is rolled, what is the probability of getting a 4?
