You are given the following information:1) The market value of a bond is estimated to be equal to the present value of all future payments from the bond at the current interest rate

2) The effective duration of a bond is a measurement of how the bond's market value responds to a change in interest rate. (e.g. A bond with duration 5 means that if interest moves by 0.1%, the market value of the bond will move by 5 x 0.1% = 0.5%)

A 5-year-tenor bond with a face value of $1000, pays an annual coupon of $25, $50, $75, $100, $125 at the end of year 1, year 2, year 3, year 4, year 5. At maturity, face value is also repaid. The current interest rate is 5% per annum, calculate the duration of this bond. 4.4 5.0 3.4 3.8

The tour operator has sold all of 21 tickets for a tour bus to DA NANG which has only 20 seats. Each ticket costs 50 and it is not refunded if a tourist does not join the tour. The probability that an individual tourist will not join the tour is 0.02. If a tourist joins the tour and there is no available seat, 100 will be refunded. What is the expected revenue of the tour operator? 985 983 933 935

A quick COVID-19 virus test detects positive results 95% of the time when the virus is actually present. This test detects positive results 0.5% of the time when the virus is not actually present. Provided that 1% of the population actually are infected by the COVID-19 virus, calculate the likelihood that a person actually is infected by the virus given that the test detects a positive result. 0.324 0.950 0.945 0.657
