7. A photon has a wavelength of 1.5 x 10-12 meters. What is this photon Solution the photon frequency in air or vacuum = c / lambda = 3x10^8 / 1.5 x 10^-12 = 2 x 10^20 Hz The photon energy, E = h * f, where h = Planck\'s constant = 6.63x10-34 [Js]. = 1.326 x 10^-13 J Double check my calculations but I think it should be ok.

6. What are the components of the KMV Portfolio Manager Model ? Solution Components of KMV portfolio Manager Model are ; Ri= AISi-E(Li)=AISi-[EDFi*LGDi] Std Dev i= ULi=Std dev di*LGDi=[EDFi(1-EDFi)]^1/2*LGDi Where AIS =Annual all in spread on a loan= (annual fees earned )+( Loan rate-cost of fund) E(L)= Expected loss on the loan EDF=Expected default frequency LGD =Loss given default UL= Unexpected Loss is a measure of Loan risk Std dev i. It is equal to the volatility of the default rate of the loan std dev di multiplied by LGD. it is also equal to the square root of the product of probability of default and 1- probability of default Correlation coeffeicicent ij= correlation between systematic return componenets of equity return of borrower i & j..

7-7. In 1895 an Italian criminologist, Cesare Lombroso, proposed that blood pressure be used to test for truthfulness. In the 1930s, William Marston added the measurements of respiration and perspiration to the process, built a machine to do the measuring, and called his invention the polygraph or lie detector. Today, the federal courts will not consider polygraph results as evidence, but nearly half the state courts do permit polygraph tests under certain circumstances. In addition, its use in screening job applicants is on the rise. Physicians Michael Phillips, Allan Brett, and John Beary subjected the polygraph to the same careful testing given to medical diagnostic tests. They found that if 1,000 people were subjected to the polygraph and 500 told the truth and 500 lied, the polygraph would indicate that approximately 185 of the truth-tellers were liars and that approximately 120 of the liars were truth-tellers ( Solution Type I Error=\"claiming that the person is liar when in fact s/he is a truth-teller\" Type II Error=\"claiming that the person is a truth-teller when in fact s/he is a liar\".

7 Children are seated randomly in a row. What is the probability that Joe and Bob sit together and Mimi and Lisa sit together, but not next to Joe and Bob? Solution total ways they can be seated = 7! now if we consider Joe and Bob sit together and Mimi and Lisa sit together the we can consider Joe and Bob as one child and Mimi and Lisa as one child no of ways they ca be seated = 5!*2*2 // 2comes as they can sit in two differnt ways next to each other no of ways they sit next to other = 4!*2 // same logic as previous consider all four as one child no of ways they dont seat nex to oher = 5!*2*2 -4!*2 probabilit = (5!*2*2 -4!*2 )/7! = .086.
