    HELP! Where do I start with Probability?

    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.

    The first thing you need to know is how LOT number are assigned. If they are random (very unlikely) it would be comparitivly simple to give an answer, but they won't be so we need to know.

    That is not enough, we need to know the method of generating them.

    A new batch of product is made the operator hits a button and a new batch number is generated with the next seq. number. (10 digits). Our warehouse system will only display 8 digits (the last eight of the 10 digit number).
