The sample space is the set of all possible outcomes (known as sample points)

An event is a subset of a sample space

 

For an event A in a sample space S

• If S is finite (countable), then
• If S is finite and  is constant for all , then
• If S is finite then

 

 

Conditional Probability

Probability of A if B is the probability of  overa the possibility for B

 

Multiplication Rule

 

Total Probability Rule

If  ...  partition S, then

Bayes' Rule

If  …  partition S, then
