When circuit boards used in the manufacture of compact disc players are tested, the long-run percentage of defectives is 5%. Let X = the number of defective boards in a randomsample of size n = 25, so X~Bin(25, .05). Determine P(X ≤ 2) Determine P(X ≥ 5). Determine P(1 ≤ X ≤ 4). What is the probability that none of the 25 boards is defective? Calculate the expected value and standard deviation of X.
