The sample space of a true
random experiment
contains all of the possible
outcomes.

, An event is a subset of the true
sample space of a random
experiment.

If a sample space consists true
of N possible outcomes
that are equally likely, the
probability of each
outcome is 1/N.

For a discrete sample true
space the probability of
an event is the sum of all
of the probabilities of the
outcomes associated with
the event.

Two events A and B are .25
independent with P(A) =
P(B) = 0.5. The P(A N B) is:

Random variables can be true
either discrete or
continuous.

Calls are repeatedly S={c, bc, bbc, bbbc, ... }
placed to a busy phone
line until a connect is
achieved. Let c=connect
and b=busy, select the
correct sample space, S,
below:

The probability mass true
function of a discrete
random variable is a
description of the
probabilities associated
with each possible value
of the random variable.
