outcomes
event
a

of
one
or
more
outcomes
sample space
set
of all the
possible
outcomes
A U B
is the probability of
A
or
B
A n
B
is the probability of
A
and
B
A'
is the probability of
Not
A
A and B are mutually exclusive
venn diagram circles
do
not
overlap
P(A U B) =
P(A) + P(B)
P (A n B) =
0
A and B are independent
one event has
no
effect
on the other
P(A n B) =
P(A) x P(B)
