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
