4 Sample Space
Double Complementation
(A^c)^c = A
Absorption
A U B = B <=> A intersect B = A <=> A is a subset of B
outcome
a final result, observation, or measurement occurring from an experiment
event
a subset of the sample space S
Elementary event
an event that is a singleton set
experiment
any process, possibly under partial control, that we may observe and for which the final state of affairs cannot be specified in advance, but for which a set containing all potential final states of affairs can be identified
sample space
denoted by S, is the set of all outcomes of an experiment. The elements of the sample space are called elementary outcomes, or sample points.
