# Math 8 Probability

#### Terms in this set (...)

Combination
An arrangement of items or events in which order doesn't matter
Compound Event
An event made up of two or more simple events
Dependent Event
Events for which the outcome of one event effects the probability of the other
Disjoint Events
when two events cannot both occur in the same trial of an experiment
Experimental probability
the ratio of the number of times an event occurs to the total number of trials, or times, that the activity is performed
Fair
When all outcomes of an experiment are equally likely. The experiment is said to be fair.
Factorial
Product of all whole numbers except 0 that are less than or equal to a number
Independent events
events for which the outcome of one event does not effect the probability of the other
Mutually Exclusive
two events that cannot both occur in the same trial of an experiment (same as disjoint)
Outcome
a possible result of a probability experiment
Permutation
An arrangement of items or events in which order is important
Probability
A number from 0-1 that describes how likely an event is to occur
sample space
all possible outcomes of an experiment
theoretical probability
the ratio of the number of equally likely outcomes in an event to the total number of possibly outcomes
Event
Any set of 1 or more outcomes
Equally Likely
All have the same probability, x, the probabilities must add to 1.
