MATH 225 STATISTICAL REASONING FOR HEALTH SCIENCES WEEK 4 PRACTICE QUESTIONS AND CORRECT ANSWERS 2024/2025 GRADED A+ . 2 / 4 1. Experiment: An action, or trial, through which specific results (counts, measure- ments, or responses) are obtained. 2. Outcome: Is the result of a single trial in a probability 3. Sample Space: The set of all possible outcomes of a probability experiment 4. Event: A subset of a sample space; It may consist of one or more outcomes 5. Simple Event: An event consisting of only one outcome 6. Fundamental Counting Principle (FCP): 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 7. Classical (Theoretical) Probability: 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 8. Empirical (Statistical) 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
