Problem
What is the difference between an outcome and an event? Choose the correct answer below. A. An outcome is the result of a single probability experiment. An event is the set of all possible outcomes. B. An event is the result of a single probability experiment. An outcome is a set of one or more possible events. C. An event is the result of a single probability experiment. An outcome is the set of all possible events. D. An outcome is the result of a single probability experiment. An event is a set of one more possible outcomes.
Solution
Step 1 ：This question is about the definitions of two terms in probability theory: outcome and event. An outcome is the result of a single trial of a probability experiment, while an event is a set of outcomes of a probability experiment.
Step 2 ：Therefore, the correct answer is D. An outcome is the result of a single probability experiment. An event is a set of one more possible outcomes.
Step 3 ：\(\boxed{\text{D. An outcome is the result of a single probability experiment. An event is a set of one more possible outcomes.}}\)
