when you perform an experiment, the probbible results are called outcomes
is a collection of outcomes
once you specifiy an event, the outcomes for that event are called favorable outcomes
The set of all possible outcomes.
You can represent a sample space by using an organized list, or a table.
An experiment with two stages or events.
Experiments with more than two stages.
Fundamental Counting Principle
Used to find the number of possible outcomes.
An arrangement of objects in which order is important.
The product of the positive integers less than or equal to n.
Objects are arranged in a circle or loop.
An arrangement of objects in which order is not important.
Probability that involves a geometric measure such as length or area.
a mathematical model used to match a random phenomenon.
The use of a probability model to recreate a situation again and again so that the likelihood of various outcomes can be estimated.
A variable that can assume a set of values, each with fixed probabilities.
Also known as mathematical expectations, is the average value of a random variable that one expects after repeating an experiment.
Consists of two or more simple events.
If the probability that A occurs does not affect the probability that B occurs.
If the probability that A occurs in some way changes the probability that B occurs.
The notation P (B/A) is read the probability that event B occurs given that event A has already occurred.
A tree diagram with possibilities.
If the two events cannot happen at the same time.
Consists of all the outcomes in the sample space that are not included as outcomes of event A.
A collection or vertices, called nodes, and segments called edges that connect the nodes.
All of the nodes are connected, and each edge is used once in the network.
