 What does P mean? Pick (permutation) order matters! What does C mean? Choose (combinations) order does not matter! When do you multiply the events by each other? If the first event can happen x ways and the second event can happen y ways, then both events can happen in the order given x times y ways. what does "!" mean? Factorial, it is used when things are repeated or identical. How do you calculate the probability of a fraction? probability of an event= # of ways that the event can occur ____________________ # of all possible outcomes What is the Bernoulli experiment? -exactly two possible outcomes -one success, one failure -fixed # of trials -trials are independent -the probability of each outcome is the same for each trial. what values must be considered? N= Number of trials R= How many times it must be successful F= # of failures S= # of successes How do you do Binomial expansion? IE: (m+2)^3 there will be 4 terms, (One more than the exponent) where a= M and b= 2 -start at zero (3choose 0..1..2..3) -then multiply everything one more time! what does P mean? pick, permutation, or exact position one more time! what does C mean? choose, combination, or committee
