Unformatted text preview: Lecture 11 27 th May 2011 Example: N balls labeled 1, 2, , N are placed in a box and n balls (n N) are randomly selected without replacement. Define the r.v. X= largest number selected Find the probability function for X and the c.d.f. Model Distributions: In the rest of the course our aim is to identify common types of processes or problems and to develop probability distributions that represent them. Where many processes or problems tend to have the same structure. For example: 1.Toss a fair coin 10 times and X records the number of heads obtained 2.Plant 20 seeds and X records the number of seeds that germinate 3.12 items are picked at random from a factory line and examined for defects. X records the number of items with no defects All these problems are essentially the same, so what is common???...
