A steel plate contains 15 bolts. Assume that 4 bolts are not torqued to the proper limit. Six bolts are selected at random, without replacement, to be checked for torque. i. What is the probability that all six of the selected bolts are torqued to the proper limit? ii. What is the probability that at least one of the selected bolts is not torqued to the proper limit?
