Terms in this set (25)
Combination
Selection of groups when the order does not matter
Complement
All outcomes in the sample space that are not in an event
Compound event
An event made up of two or more simple events
Conditional probability
Probability of an event given that another event has already occurred
Conditional relative frequency
Ratio of joint relative frequency to a marginal relative frequency
Dependent events
Events when the one event affects the outcome of the second event
Equally likely outcomes
Events with the same probability
Event
An outcomes or set of outcomes in a probability experiment
Experiment
An operation, process, or activity in which outcomes can be used to estimate probability
Experimental probability
The ratio of the number of times an event occurs to the number of trials
Factorial
The number times all the numbers before it
Favorable outcomes
The occurrence of one of several possible outcomes of a specified event or probability experiment
Geometric probability
A form of theoretical probability determined by a ratio of geometric measures such as lengths, areas, or volumes
Inclusive events
Events that have one or more outcomes in common
Independent events
Events where the one event does not affect the probability of the other event
Joint relative frequency
The ratio of the frequency in in a particular category divided by the total number of values
Marginal relative frequency
The sum of the joint relative frequencies in a row or column of a two way table
Mutually exclusive events
Two events are mutually exclusive if they both cannot both occur in the Same trial of an experiment
Outcome
A possible result of a probability experiment
Permutation
Arrangement of a group in which the order is important
Probability
A number from 0-1 that is the measure of how likely an event is to occur
Sample space
The set of all possible outcomes of a probability experiment
Simple event
An event consisting of only one outcome
Theoretical probability
Ratio of number of likely outcomes to the total number of possible outcomes
Trial
In probability, a single repetition or observation of an experiment
