What is the probability that all three orders will be filled correctly? The probability is 0.3890 (Round to four decimal places as needed.) b. What is the probability that none of the three orders will be filled correctly? The probability is 0.0197. (Round to four decimal places as needed.) c. What is the probability that at least two of the three orders will be filled correctly? The probability is 0.8207 (Round to four decimal places as needed.) d. What are the mean and standard deviation of the binomial distribution used in (a) through (c)? Interpret these values The mean is (Round to four decimal places as needed.)
