Being really bad in Statistics, need some help here. The problem is : We draw a sample of 20 laptops from a population of 1000 Laptops (serial numbers from 9000-9999). a. What distribution should i use for the serial number selected? b. What is the probability a randomly selected will be one of the last 200 to be produced. c. What is the probability the first 2 are from the last 100 to be manufactured. ** The purpose of sampling is to check the quality of the laptops, thus there are two outcomes: faulty or not-faulty.
