classical probability - ANSWER -the type of probability that uses sample spaces to
determine the numerical probability that an event will happen
combination - ANSWER -a selection of objects in which order is not important
complement of an event - ANSWER -consists of all possible outcomes in a sample space
that are NOT part of the event
conditional probability - ANSWER -the probability that an event B occurs after an event A
has already occurred
P(B/A)
dependent events - ANSWER -events for which the outcome or occurrence of the first
event affects the outcome or occurrence of the second event in such a way that the probability
is changed
empirical probability - ANSWER -the type of probability that uses frequency distributions
based on observations to determine numerical probabilities of events
equally likely events - ANSWER -the events in the sample space that have the same
probability of occurring
, event - ANSWER -A subset of a sample space.
fundamental counting rule - ANSWER -In a sequence of n events in which the first one
has k1 possibilities and the second event has k2 and the third has k3, and so forth, the total
number of possibilities of the sequence will be
k1 · k2 · k3 · · · kn
Note: In this case and means to multiply.
independent events - ANSWER -events for which the probability of the first occurring
does not affect the probability of the second occurring
law of large numbers - ANSWER -when a probability experiment is repeated a large
number of times, the relative frequency probability of an outcome will approach its theoretical
probability
mutually exclusive events - ANSWER -probability events that cannot occur at the same
time
outcome - ANSWER -the result of a single trial in a probability experiment
permutation - ANSWER -an arrangement of n objects in a specific order
probability - ANSWER -the chance of an event occurring
probability experiment - ANSWER -a chance process that leads to well-defined results
called outcomes
sample space - ANSWER -the set of all possible outcomes of a probability experiment
simple event - ANSWER -an outcome that results from a single trial of a probability
experiment
