23 Cards in this Set

  • Front
  • Back
set
a well defined collection of objects (represented by a captial letter)
elements
the objects in a set (represented by a lower case letter)
equal sets
2 or more sets that contain exactly the same elements; the order in ehich the elements are listed in irrelevent
empty or null set
the set that contains no elements
universal set
the set of all elements of interest in a particular discussion
disjoint sets
sets that have no elements in common; the intersection of a disjoint set is the nullset
complement of a set A
the set of all elements in the universal set the do not belong to the set A
A is a subset of B
if A__B then every element in A is in B ans A can be equal to B
A is a proper subset of B
is A__B, then every element in A is in B and A must be "smaller" than B
Experiment
an activity with abservable results
trial
each repetition of an experment
__
an element of the set
__
not an element of the set
__
a subset of the set
__
a proper subset of the set
sample space
the set of all possible outcomes of an experiment (in set theory this was the universal set)
simple outcome
(sampile point)
the result of an experiment or a single element in the sample space
event
a subset of the sample space(a set of outcomes)
mutually exclusive events
(M.E.)
events that have no outcomes in common(the therm used in set theort was disjointed sets)
certain event
an event that has a probability of 1.0
impossible event
an event that has a probability of 0
theoretical probability
the probability that is assigned to an event throught the use of theoretical means (i.e. equations or formulas)
empirical probability
the probability that is assigned to an event using past experiences of the gathering data
