Probability Experiment (Trial) - ANSWERany process with a result determined by
chance

Outcome - ANSWERindividual result possible from a probability experiment

Sample Space - ANSWERset of all possible outcomes for a probability experiment

Event - ANSWERsubset of outcomes from the sample space

Sample Space Example - ANSWER-roll a six sided die
{1,2,3,4,5,6}
-{}- set notation

Notation of Sample Space - ANSWER-"S" capital

Denote an Event with - ANSWER-a letter such as A,B,C, etc.
-Probability that event E occurred it denoted by: P(E)

Experimental (Emperical) Probability - ANSWERperform the experiment a large
number of times

Experimental Probability Example - ANSWERFruitfly experiment

Classical (Theoretical)Probability - ANSWERif all possible outcomes in the sample
space are known and equally likely to occur

Classical Probability Example - ANSWERtoss two die, what is the probability that the
sum of the die is greater than 10?
Ans: (5,6), (6,5), (6,6)
A= sum >10
P(A) =3/36

4.2 - ANSWERAddition Rules


Multiplication Rules - ANSWER-P(AnB) = (P/A)P(B) or other way
-If independent:
P(AnB)=P(A/B)P(B) = P(A)P(B)

4.4 - ANSWERCounting Rules (Combinations and Permutations)
