1)Assume that the service life in years of a semiconductor is arandom variable that has the Weibull distribution with alpha = 5and beta = 3. What is the probability that a semiconductor likethat will still be in operational condition between 3.7 and the 5years?
2)Assume that the service life in years of a semiconductor is arandom variable that has the Weibull distribution with alpha = 2and beta = 4. What is the probability that a semiconductor likethat will still be in operational condition until 4.9 years ?
