A random experiment has sample space S = {a, b, c, d}. Suppose
that P({c, d}) = 3/8, P({b, c}) = 6/8, and P({d}) = 1/8. Use the
axioms of probability to find the probabilities of the elementary
events.

8: An experiment has three possible elementary outcomes a, b,
and c. Thus, the sample space is S = {a, b, c}. Define three events
E1 = {a, b}, E2 = {a, c}, and E3 = {b, c}.
Let us also define a probability measure to have values P[E1]
=2/3, P[E2] =1/3, and P[E3] =1/3.

Let the S = {0,1,2,3,4,5,6,7,8,9,10} be the sample space of a
random experiment. Suppose A is the event that we observe a number
less than 3 and B be the event that we observe a number greater
than 8. Determine the event that either A occurs or B occurs.

A probability experiment is conducted in which the sample space
of the experiment is S={7,8,9,10,11,12,13,14,15,16,17,18}, event
F={7,8,9,10,11,12}, and event G={11,12,13,14}. Assume that each
outcome is equally likely. List the outcomes in F or G. Find P(F or
G) by counting the number of outcomes in F or G. Determine P(F or
G) using the general addition rule.

A Bernoulli trial is an experiment with the sample space
S = {success, failure}. Let X be the random variable on S
defined by
? X(s) : 1 if s = success
0 if s = failure.
Suppose the probability P ({success}) is equal to some value p ∈
(0, 1).

4. For the following claims, state whether they are TRUE or
FALSE. Statements claimed to be TRUE must be accompanied by a
proof, and statements claimed to be FALSE must be accompanied by a
counterexample.
(a) Let A and B be events in the sample space S. Then P(A ∩ B) ≤
P(A)P(B).
(b) Let E be an event with 0 < P(E) < 1 and define PE(A) =
P(A ∩ E) for every event A in the sample space...
