1. Random Experiments and Trials

Key Concepts & Definitions

  • Random experiment: A random experiment is a repeatable process where uncertainty remains and the set of possible outcomes is known.
  • Trial: A trial is one single execution of a random experiment, producing one observed result.

Essential Points

  • A business example of a random experiment is the number of customers in a day for a store because it is uncertain, repeatable, and has known possible outcomes.
  • In a random experiment, uncertainty comes from not knowing which outcome will occur before the trial happens.
  • Opening the store every morning can be the random experiment, while the number of customers on a given day is the trial.
  • In a business context, one trial can be one customer visit, one loan default, or one day of sales.

Memory Hook

Experiment = the procedure; trial = the one run that happens.
