3. Suppose that A and B are two events defined over the same sample space, with probabilities P(A) 3/4 and P(B)- 3/8. (a) Show that P(A UB) 2 3/4. (b) Show that 1/8 < P(AB) 3/8 (c) Give inequalities analogous to (a) and (b) for P(A) 2/3 and P(B)1/2.
If a sample space consists of 8 outcomes, then the number of events containing 3 outcomes is A) 56 B) 336 A C) 112 D) 168 E) 84
A committee of 2 people is to be selected from 6 executives, Alam, Bartolini, Chinn, Dickson, Elsberg, and Francis. Write out the sample space S, choosing an S with equally likely outcomes, if possible. Then give the value of n(S) and tell whether the outcomes in S are equally likely. Finally, write the indicated events below in set notation. a. Ellsberg is on the committee. b. Alam and Bartolini are not both on the committee. c. Both Bartolini and Chinn...
1. Events A and B are defined on a sample space S such that P((A ∪ B) C) = 0.5 and P(A ∩ B) = 0.2.If P(A) = 0.3, what does P((A ∩ B) | (A ∪ B) C) equal?
4.1-1. Two events A and B defined on a sample space S are related to a joint sample space through random variables X and Y and are defined by A = {X < x) and B = {y <Y < y2). Make a sketch of the two sample spaces showing areas corresponding to both events and the event A B = (X < x, y <Y < y2}.
Let A and B be events in the same sample space, such that Pr[A] = 2/5, Pr[B] = 3/10, and Pr[A|B] = 2/3. What is Pr[B|A]? Thank you :)
Let A, B, and C be three non-empty events defined on the sample space S, illustrated below. Find an expression for the case where two or more events occur? a. b. c. d.
Let A, B and C be three events defined on a sample space S (for the purposes of illustration assume they are not disjoint as shown on the Venn diagram below). Find expressions and draw the Venn diagram for the event, so that amongst A, B and C: a. only A occurs b. both A and B occur, but not C c. all three events occur d. none of the events occurs e. exactly one of the events occurs f....
2. Suppose A, B, and C are events of strictly positive probability in some probability space. If PAC) 〉 P(BC) and P(A|Cc) 〉 P(BİC"), is it true that P(A) 〉 P(B)? If P(AC) > PlAIC") and P(BIC) > P(BIC"), is it true that P(An BC) > P(An BIC)? 2. Suppose A, B, and C are events of strictly positive probability in some probability space.

5. You roll a red die and a blue die. How many simple events (or outcomes) are there in the sample space?
