MATH 225 - STATISTICAL REASONING FOR
THE HEALTH SCIENCES WEEK 4 QUESTIONS
AND VERIFIED CORRECT ANSWERS




An action, or trial, through which specific results (counts, measurements, or responses) are obtained. -
answer ✔✔-Experiment



Is the result of a single trial in a probability - answer ✔✔-Outcome



The set of all possible outcomes of a probability experiment - answer ✔✔-Sample Space



A subset of a sample space; It may consist of one or more outcomes - answer ✔✔-Event



An event consisting of only one outcome - answer ✔✔-Simple Event



if one event can occur "m" ways and a second event can occur "n" ways, then the number of ways that
two events can occur together is m x n - answer ✔✔-Fundamental Counting Principle (FCP)



Used when each outcome in a sample space is equally likely to occur



P(E) = Number of outcomes in event E / Total number of outcomes in sample space - answer ✔✔-
Classical (Theoretical) Probability



Expressed as the frequency of an event divided by the total frequency. It is based on observations
obtained from probability experiments.



P(E) = Frequency of event E / Total frequency ; =f/n - answer ✔✔-Empirical (Statistical) Probability
