independent events
events for which the outcome does not affect the probability of the other. (think: with replacement) (P(A and B ) = P(A) * P(B) )
dependent events
events for which the outcome of one event DOES EFFECT the probability of the other. (think: without replacement) (P(A and B)= P(A) * P (B after A) )
favorable outcome
an outcome that you are looking for when you conduct an experiment
theorectical probability
number of favorable outcomes, number of possible outcomes
fair
if each possible outcome in an experiment is equally likely to occur
probability
the measur of how likely an event is to occur.
experiment
an activity involving chance
outcome
the result of an experiment
event
a set of one or more outcomes
sample space
total amount of possible outcomes
tree diagram
a branching diagram that shows all possible outcomes of an event
Counting Principle
states that you can find the total number of ways that two or more seperate tasks happen multiplying the number of ways each task can happen seperatly.
experimental probability
is based on conducting experiments of making observations
trial
a single repetition or observation of an experiment
combination
a group and of objects or events in which DOES NOT matter
