As shown in the Venn diagram below, B and Care events in the sample space S. Indicate the event B by shading the appropriate region(s). (If necessary, consult a list of formulas.) S + B x 5 ?
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...
