I work in a warehouse and have been ask to figure the probabilty to this issue. (Two parts)
(Part one) Our products have 9 and 10 digits LOT numbers assigned at each manufacturing plant (9 plants). What is the probability that two different products lot numbers would have the same last 8 digits?
(Part two) What is the probabilty that the two products with the same last 8 digits of their lot numbers would be stored next to each other in the warehouse?
What information do I need in order to figure this out?
Thanks in advance.
