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 random sample of size n = 25, so X ~ Bin(25, 0.05). (Round your probabilities to three decimal places.)
(a) Determine P(X <_ 2).(b) Determine P(X >_ 5).(c) Determine P(1 <_ X <_ 4).(d) What is the probability that none of the 25 boards is defective?
