Independent events occur when the outcome of one event does not affect the outcome of another. For example, flipping a coin and rolling a die are independent actions. Worksheets often include problems like calculating the probability of rolling a 3 on a die and flipping a head on a coin. The formula for independent events is P(A and B) = P(A) × P(B). Students practice these calculations with exercises involving multiple dice rolls, card draws, or marble selections, ensuring a solid understanding of how independent probabilities interact and combine.
2.3 Probability of Multiple Events
Multiple events in probability involve calculating the likelihood of two or more events occurring together. Worksheets often include scenarios like drawing two marbles without replacement or flipping a coin multiple times. For independent events, the probability is the product of individual probabilities (P(A and B) = P(A) × P(B)). For dependent events, the probability of the second event depends on the first. Exercises include problems like selecting a red marble and then a blue marble, with answers provided to guide students through these calculations and deepen their understanding of combined probabilities.
2.4 Understanding Probability Scales
Probability scales are visual tools used to represent the likelihood of events occurring, ranging from 0 (impossible) to 1 (certain); Worksheets often include exercises where students plot probabilities on number lines or charts.

Conditional Probability
Conditional probability calculates the likelihood of an event based on another event occurring. It uses the formula P(A|B) = P(A ∩ B) / P(B), with practical examples in worksheets.
3.1 Definition and Examples
Conditional probability refers to the likelihood of one event occurring based on another event happening. It is calculated using the formula P(A|B) = P(A ∩ B) / P(B).

4.3 Comparing Theoretical and Experimental Probability
Comparing theoretical and experimental probability helps verify the accuracy of probability predictions. Theoretical probability is calculated based on the number of possible outcomes, while experimental probability is derived from repeated trials. For example, flipping a fair coin theoretically has a 0.5 chance of landing heads, but experimental results might show slight variations. Worksheets often include problems where students calculate both probabilities and analyze any discrepancies. This comparison enhances understanding of probability concepts and highlights the role of trials in approximating theoretical probabilities. It also encourages critical thinking about data consistency and real-world applications.
