STAT AND PROB LESSON 1

• A procedure that generates observable outcomes.

  Experiment
• Any possible observation of an experiment.

  Outcome
• The set of all possible outcomes in an experiment.

  Sample Space
• A function whose domain is the sample space of a random experiment, and the range of the values is the set of real numbers.

  Random variable
• A variable whose possible values are determined by chance.

  Random variable
• Variables that take on a finite number of distinct values.

  Discreet Random variable
• Can be counted

  Discreet random variable
• Values that take on an infinite number of distinct values.

  Continuous random variable
• Cannot be counted

  Continuous random variable
• What is the formula for the probability?

  Number of desired outcomes divided by the number of possible outcomes
• Property 1 of Probability

  The probability is greater than or equal to 0 but is less than or equal to 1
• Property 2 of probability

  The sum of all probability is 1
• Symbol for Sample Space

  S
• symbol for the number of elements in a sample space

  n(S)
• Symbol for probability

  P(e)
