Answer 1

Answer #1

a)for above to be worked: P= (1-12 not work*34 not work)*5 works =(1-(1-0.4*0.7)*(1-0.5*0.3))*0.2=0.0776

b)in same manner probability that current flows =p1p4+p1p3p5+p2p5+p2p3p4-p1p3p4p5-p1p2p4p5-p1p2p3p4-p1p2p3p5-p2p3p4p5+p1p2p3p4p5 =0.2936

Question 4. Consider the electrical circuit depicted below. Current will flow from a to b if there is at least one closed path when the relays are switched to "closed". However, the relays may malfunction. Suppose the probability that the three relays depicted below close properly are: Pi = 0.9, P2 = 0.85 and P3 = 0.95, respectively. All relays operate independently of each other and are mutually independent as well. Let A denote the event that current will flow...

Let p=(p1,p2,…,pm) be a probability distribution over m possible outcomes. The entropy of p is a measure of how much randomness there is in the outcome. It is defined as where ln denotes natural logarithm. We wish to ascertain whether F(p) is a convex function of p. As usual, we begin by computing the Hessian. A) Consider the specific point p=(1/m,1/m,…,1/m). What is the (1,1) entry of the Hessian at this point? Your answer should be a function of m....
