please help with this problem, thank you!

You may need to use the appropriate technology to answer this question. A lawn and garden shop that is open for business seven days a week orders bags of grass seed every other Monday. Lead time for seed orders is five days. On Monday, at ordering time, a clerk found 93 bags of seed in stock, so he ordered 207 bags. Daily demand for grass seed is normally distributed with a mean of 16 bags and a standard deviation of four bags. The manager would like to know the prababilsy that a graws seed stockout will occur before the next order arrives. (Round your answer to four decimal places.)
