Study Notes

  • Simulation models random events to match real-world outcomes.

Building a Model

  • Component: The most basic event in a simulation.
  • Trial: A sequence of events that are simulated.
  • Response Variable: What is recorded about each trial.

Conducting a Simulation

  • Identify the component and how to model its outcome.
  • Explain how to simulate a trial, outlining all steps.
  • State the response variable clearly.
  • Run several trials.
  • Analyze the response variable.
  • State the conclusion in relation to the real-world question.

Random Numbers

  • Must be random and independent.

Getting Random Numbers

  • Table of Random Digits
  • Random Number Generators

TI-84

  • randInt(min, max, number of trials)
  • randNorm(mean, standard deviation, number of trials)

Probability

  • Definition: The long-run relative frequency of an event.

Formal Probability

  • For any event A, the probability of A is between 0 and 1: $0 \leq P(A) \leq 1$.
  • The probability of all possible outcomes is 1: $P(S) = 1$
  • Complement Rule: The probability of an event not occurring is $P(A^c) = 1 - P(A)$.
  • Addition Rule: For disjoint events A and B, $P(A \cup B) = P(A) + P(B)$.
  • Multiplication Rule: For independent events A and B, $P(A \cap B) = P(A) \times P(B)$.
