probability
terms
experiment
any activity that produces or observes an outcome
sample space
the set of possible outcomes for an experiment
event
a subset of the sample space
formal features
(if P(Xi) is the probability of event Xi
probability cannot be negative, P(Xi) >= 0
the total probability of all outcome is 1,
sum(P(Xi), N, i=1) = 1
the probability of any individual event cannot be greater than one P(Xi) <= 1
how to determine
personal belief
empirical frequency
classical probability
rule of subtraction
P( ¬A) = 1 - P(A)
intersection
P(A∩B) = P(A) * P(B), if only A and B are independent event
