Probability Simulations NOTES & PRACTICE

Select a simulation tool (coin, spinner, number cube, or random-digit generator) that models the probabilities of the outcomes in a given real-world event.

Calculate an experimental probability from simulation trial results and compare it to the theoretical probability of the same event.

Evaluate whether a proposed simulation design would produce valid results for a described situation.

Work through Example 1 (predicting a family's birth order with a coin) as a class before assigning the remaining three examples independently, since the notes model the tool-selection reasoning there first.

Use the six true/false statements as a quick check for misconceptions — such as the belief that a simulation should always match real-life data exactly — before moving to the practice problems.

Have students work through the supplied random-digit tables and complete the trial records before checking the answer key.

Simulation-tool selection — students assign tool outcomes to represent the probabilities in a real event (e.g., a two-sided coin for a 50/50 birth-order event).

Experimental-versus-theoretical probability comparison — examples and test questions compare experimental results with theoretical probabilities.

Data interpretation from simulation trials — students read tables of trial results (e.g., 50 trials of a coin flip) and compute a probability from the recorded outcomes.
