Factorial --
a mathematical expression n!
which means the product of the number n with all the natural
numbers less than n
Fair --
an object, game, or experiment where all of the outcomes are
equally probable
Fundamental
Counting Principle -- if event A can occur a ways
and event B can happen b ways, then event A followed
by event B can occur in a*b ways using the multiplication
rule
Impossible
event -- probability of
the event is exactly equal to zero; the event absolutely cannot
happen
Independent events
-- two events that do not affect each other (like day of the
week and temperature)
Joint probability
-- multi-stage or multi-object, with or without replacement,
use the multiplication rule
Multiplication
rule -- for multi-stage experiments, the probability of
two or more events happening is equal to the product of their
individual probabilities
