    Help identify distribution and estimate CDF

    I am looking to solve the problem for a case study:
    The Company sells N units of merchandise over the period of T
    Some of the units are returned. For each unit I have Sale date and return date (if returned)

    I need to derive a distribution which looks like this:

    P1% propability that no units are returned
    P2% probability that Q1% units are returned
    P3% probability that Q2% units are returned
    ...
    Pn% probability that Q(n-1)% units are returned

    P1+...+Pn = 100%

    Could you help me identify which distribution is that and how to go about estimating Pi and Qi? Can I use Excel for it?
    Any suggestions welcome
