Problem 2 Consider two arbitrary events, E and F. The new event, G = EAF, occurs when one of the two events occurs but...
1. Consider a statistical experiment E: (, F,P) and an event A . Note: A EF. a. Use the axioms of probability to show that P(A) 1-P(A). b. Repeat (a) using the definition of the σ-field. 2. Consider a statistical experiment E: (, F,P) in which a fair coin is flipped successively until the same face is observed on successive flips. Let A = {x: x = 3, 4, 5, . . .); that is, A is the event that...
Problem 7: 10 points Assume that events (E, F) are disjoint, and their probabilities are specified as (here p+q1). An experiment is repeated until either E or F will occur Find the probability that E will occur before F Hint Introduce a random variable, N, which is the first occurrence of EUF. Then express the probability that E occurs before F, given that EUF occurs at the time and use the formula where A is the desired event.
Problem. (Section 1.2). Let E, F, and G be events in a sample space S. Determine which of the following statements are true. If true, prove it. If false, provide a counterexample. (a) (E − EF) ∪ F = E ∪ F (b) F'G ∪ E'G = G(F ∪ E)' (c) EF ∪ EG ∪ F G ⊂ E ∪ F ∪ G
1. Time-Like, Null, and Space-like Intervals Events E, F, and G in an inertial reference frame have (t, z) coordinates as follows, Note that we're measuring both space and time coordinates in consistent units, i.e. (a) (4 points) Draw a spacetime diagram with the three points marked and labeled. (i) Is the interval between the two events time-like, null, or space-like? seconds and light-seconds, or light-metres (a unit of time!) and metres. Answer the following questions for the pair of...
In this problem we consider only functions defined on the real numbers R. A function f is close to a function g if 3x E R s.t. Vy E R, A function f visits a function g when Vz E R, R s.t. a<y and f() -g) For a given function f and n E N, let us denote by n the following function: n(x)-f(x)+2" Below are three claims. Which ones are true and which ones are false? If a...
Question 1 (20 points: Events, counting, and properties f probabniny Consider the network shown below. There are two kinds of links in the network. Each link of kind o-p +0 fails with probability p and that of kind O 4+0 fails with probability q. Each link is assumed to fail independently of the other. We say that a path is successful if no link in the path fails. For example, the path S-B-T succeeds if none of the links S...

Hi, I could use some help for this problem for my discrete math class. Thanks! 18. Consider the graph G = (V, E) with vertex set V = {a, b, c, d, e, f, g} and edge set E = {ab, ac, af, bg, ca, ce) (here we're using some shorthand notation where, for instance, ab is an edge between a and b). (a) (G1) Draw a representation of G. (b) (G2) Is G isomorphic to the graph H -(W,F)...
A financial manager made two new investments—one in the oil industry and one in municipal bonds. After a one-year period, each of the investments will be classified as either successful or unsuccessful. Consider making the two new investments as an experiment with the following four experimental outcomes. Experimental Outcomes Oil Industry Municipal Bond E1 Successful Successful E2 Successful Unsuccessful E3 Unsuccessful Successful E4 Unsuccessful Unsuccessful a. How many sample points exist for this experiment? b. Choose a tree diagram. Let...
