  Normal Size     Small Size show me how



sample space all possible outcomes or results ex. tossing a coin: P(h) = 50% P(t) = 50% sample space = {head, tail}
outcome the result of a single trial of an experiment
event a group of outcomes - - roll an even number on a die (outcomes 2,4,6)
probability a measurement of how likely an event is- the number of ways it can happen/total outcomes
complement all outcomes in an event that did not occur
independent event an event not affected by a previous event- flipping a coin
dependent events conditional probability an event affected by a previous event - pulling different color socks from a drawer, the probability changes unless you return the one you pulled out
mutually exclusive events that can not happen together - a coin flip can not result in heads and tails
experiment has an unknown outcome
tree diagram looks like a factor tree, used to calculate the probability of both independent and dependent events
tree diagram continued! tree diagrams for dependent events are like a dichotomous key for classification
ratio shows relative size of two numbers - can be part to whole (like a fraction) or part to part - can be written in various forms 1:3. 1/3, 1 to 3
proportion a statement that says two ratios (or fractions) are equal - 2:3 = 8:12
