-Chapter 2: Let A, B and C be non-disjoint events consisting of elements from the sample space Ω. Using only the operators for union (U), intersection (n), difference () and complement (C) as well as the letters A, B and C write down expressions for events A, B and C where 1. At least one event is true. 2. Only the event A is true. 3. A and B are true but C is not 4. All events are true....
Suppose A and B are events in a sample space Ω. Let P(A) = 0.4, P(B) = 0.5 and P(A∩B) = 0.3. Express each of the following events in set notation and find the probability of each event: a) A or B occurs b) A occurs but B does not occur c) At most one of these events occurs
2. Given the sample space: Ω = {a,b,c,d) and events: A-(a, b, c} and B {b, c, d} Calculate and compare both sides of De Morgan's Laws:
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....

Problem 1.1 Let A, B, C be three events in a sample space S. Each of the statements belovw describes an event built from events A, B, and C. For each statement, express the resulting event in terms of the events A, B, and C using only the complement, union, and intersection operations. Also, for cach statement, draw an appropriate Venn diagram and shade the resulting event. (There may be several ways to write the same statement, you only need...

Problem 1.2 Consider an experiment with sample space S = {1,2,3,4}. Define events A, B, C as A = {1,2}, B = {2,3}, C = {1,4}. (a) Are A, B, C mutually disjoint? Are A, B, C collectively exhaustive? (b) Is it possible to have P[A] + P[B] + P[C] = 1? Explain why or why not. (c) If P[A] + P[B] + PIC] = 1, what is the value of P[A]?
The events A, B and C form a partition of the sample space 2. Suppose that we know that P(A U B) 5/8 and that P(B U C) 7/8. Find P(A) P(B) and P(C); explain how you arrive at your answers.
2. Express each of the following events in terms of the events A, B, and C, and the operations of complementation, union, and intersection: (a) at least one of the events A, B,C occurs; (b) at most one of the events A, B, C occurs; (c) none of the events A, B, C occurs; (d) all three events A, B, C occur (e) exactly one of the events A, B, C occurs; (f) events A and B occur, but not...
