are you referring to the probabilities used in TPC-W? I'm not familiar
with the details of the benchmark, you could look for documents on the TPC
web site for example. if you had the server logs from a run of the TPC-W
workload, you could extract the individual sessions and estimate the
probabilities that were used.

you could define many different sessions (--wsesslog), and use think times
within the log file of sessions to control the request rate. It takes
some thought, but it can be done.
