2 Question 2 When circuit boards used in the manufacture of compact disc players are tested, the probability that a given disk is defective is 5%, independent of all other disks. Assume you are running quality control, and are testing a random sample of 25 disks. a. Let X be the number of defective disks in a sample of 25. What is the distribution of X? (Its name and parameters are suicient for this problem) b. Determine the probability that there are 4 or more defective disks in the sample. c. Determine the probability that there is between 1 and 3 (inclusive) defective disks in the sample
