A machine produces 1000 steel O-rings per day. Each ring has probability 0.9 of meeting a thickness specification. Use central limit theorem and normal approximation to binomial to answer the following questions. What is the probability that on a given day, fewer than 890 O-rings meet the specification? 
 Find the 60th percentile of the number of O-rings that meet the specification. 
 If the machine operates for five days, what is the probability that fewer than 890 O-rings meet the specification on three or more of those days?
