... times, where Side i comes up with probability pi = ci /c. The probability that side i comes up ki times is given by the expression above. Now relating it back to the Poisson process that we have, each side corresponds to an interval that we sample, and the probability that we sample it depends direc ...

... 4. The dot location of the yarn, as related to the size of the pieces of the yarn cut for any particular customer, can be viewed in light of the random incident paradox. (a) Here, the length of each piece of yarn is exponentially distributed. As explained on page 298 of the text, due to the memoryle ...

... • There is a certain relationship between Exponential and Poisson distributions. To wit, exponential distribution can be derived from Poisson distribution. We will explore this relationship in the section for the Exponential distribution. Exponential and Poisson distribution are both useful in model ...
