Document Summary
Common discrete distributions, bernoulli variable and binomial distribution. Rules and terms of probability: probability, the chance that an uncertain event will occur o always between 0 and 1 o if an event has n likely outcomes, then for any event a: P(a) = (# of ways event a can occur)/(all possible outcomes) {1, 2, 3, 4, 5, 6} o example 3: all 52 cards of a bridge deck. {(cid:1005) , (cid:1006) , (cid:1007) , (cid:1008) , (cid:1009) , (cid:1010) , (cid:1011) , (cid:1012) , (cid:1013) , (cid:1005)(cid:1004) , j , q , k , (cid:1005)(cid:1488), 2(cid:1488), 3(cid:1488), 4(cid:1488), 5(cid:1488), 6(cid:1488), 7(cid:1488), 8(cid:1488), 9(cid:1488), 10(cid:1488), j(cid:1488), q(cid:1488), k(cid:1488), 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 52: tree diagrams, diagram that shows branches of possible outcomes, example: here is a tree diagram for the table above.
