P(AUB) = P(A) + P(B) P(AUB) -




Multiplication Rule for independent
events


Law of Large Numbers -
the relative frequency of an outcome
converges to a number , the probability
of the outcome , as the number of observed
outcomes increases

sample space -> every single category (5 )
=




P(A) =
amount in Category A
total amount of categories

Complement of A: A is everything except A
in the sample space (1- ) ...




P(AUB) =
P(A) + P(B) -




P(A1B)
& &
A Or B intersection

, DDISjO Events are mutually exclusive ,
they have no common outcome
↳ yes if P(A1B)
= 0
alla all points are
EITHER A Or B


Two events are independent if the outcome
of one event does not affect the chances
of the outcome of the other event
↳ multiplication rule P(A) .

P(B)




the relative frequency of an outcome
converges to a number , the probability
of that outcome , as the number of
observed outcomes increases
