chapter 3.3 compound events Flashcards
disjoint or mutually exclusive
events that cannot occur at the same time for one outcome of an experiment
addition rule
states p (a or b) = p (a) +p(b)-p (A and B ) or P(a U B ) = P (a) + p (B)- p (a U B)
where is the probability at least one of the events occur in an outcome and P ( a and b is the probability that both a and b occur at the same time in an outcome
conditional probability
is the probability that results after another event has already happened and could effect the new event
dependent
if two events affect the occurrence of each other
independent
if two cents dont affect the occurenceof each other
multiplication rule
the probability of the intersection of events a and b is given
probability distribution
a table which lists all outcomes and the probabilities
