Chapter 3 Sec1 Probability Terms Flashcards
The set of all possible outcomes of a probability experiment
Sample space
The result of a single trial in a probability experiment
Outcome
A subset of the sample space
Event
An event that consists of a single outcome
Simple event
Find number of outcomes in a sample space without finding the sample space
Fundamental counting principle
Used when each outcome in a sample space is equally likely to occur
Theoretical probability
Based on data
Empirical probability
An expert opinion
Subjective probability
The more trials completed if an experiment, the closer the empirical probability gets to the theoretical probability
Law of large numbers
When the probability of the event is 1
Certain event
When the probability of the event is zero
Impossible event
Set of all outcomes in a sample space that are not included in the event
Compliment of an event
What does the probability of an event and the compliment of an event equal when added together
One
What two values is probability between
0 and 1
What does the sum of all probabilities for an experiment equal
1
What is the sample space in relation to probability
The denominator
What is theoretical probability also called
True or classical
What is empirical probability also called
Statistical
Always going to happen
Certain event
Never going to happen
Impossible event
What is the notation for the compliment of an event
The derivative sign or the bar above the letter
_
( A’ or A )
