Homework Answers
a) for 50 year wind, probability of exceeding in a given year =1/50 =0.02
P(first time in 5th year )=P(does not exceed in first 4 and exceed in 5th year) =(1-0.02)^4*0.02 =0.0184
b)
P(wthin 5 year )=1-P(does not occur in first 5 year ) =1-(1-0.02)^5 =0.0961
c)
P(exactly one in first 5 year) =(5C1)*(0.02)1*(0.98)4 =0.0922

4.29 A structure is designed with a capacity to withstand a wind velocity of 150 kph; i.e., any wind velocity up to 150 kph will not cause damage to the structure. In a hurricane-prone area, the maximum wind velocity during a hurricane may be modeled as an extreme Type / asymptotic distribution with a mean velocity of 100 kph and a c.o.v. of 0.45. (a) For a structure with the above wind-resistant capacity, what would be the probability of wind...

A system (e.g. a dam or a dike) is said to be designed for the N-year flood if it has a capacity which will be exceeded by a flood equal or greater that the N-year flood. The magnitude of the N-year flood. The magnitude of the N-year flood is that which is exceeded with probability 1/N in any given year. Assume that successive annual floods are independent. a)- What is...

An offshore structure with a design life of 20 years is planned for a site where extreme wave events may occur with a return period of 100 years (i.e. the 100-year wave). The structure is designed to have a 0.99 probability of not suffering damage within its design life. Damage effects between wave events are statistically independent (a) You found in HW 4 that the yearly probability of exceedance of the design wave height is p = 1/100 = 0.01....

5. Recidivism According to the Scientific American article "Reducing Crime: Rehabilitation is Making a Comeback," R. Doyle examined rehabilitation of convicted felons. One aspect of the article discussed recidivism of juvenile prisoners between 14 and 17 years of age, indicating that 82% of those released in 1994 were rearrested within 3 years. Suppose that today, 25 newly released prisoners between 14 and 17 years old are selected at random for monitoring over the next 3 years. a. Assuming that the...

Joe Smith is a 69-year-old male with a 50-year history of
smoking 2 packs of cigarettes a day (i.e. 100-pack-year smoking
history). Over the past 5 years, he has become increasingly short
of breath. At first, he noticed this only when exercising, but now
he is even short of breath at rest. Over the past two years, he has
had several bouts of lower respiratory tract infection treated
successfully with antibiotics. His shortness of breath hasn't
subsided, and his breathing...
