Bаsed оn the histоricаl dаta, a mail-оrder company determined and now advertises that it ships 90% of its orders within three working days of receipt of the order. Correspondingly, for 10% of orders it takes more than three working days to be shipped. Last month the company received 10,000 orders. The company is planning an audit of 100 randomly chosen orders from last month. The random variable represents the number of orders shipped within more than three working days in the sample of audited orders and follows the binomial distribution. You are asked to calculate the probability that, during the audit, 15 orders will reveal that it took more than three working days to get them shipped. What is the number of trials and the probability of success you will use to calculate this probability?
