[R] Poission distribution

[Ethan Johnsons]

The expected number of bladder cancer over next 20 years a tire
industry is 1.8.  Poission distribution is assumed to hold and 6
reported deaths are caused by bladder cancer among the employees.
Trying to find how unusual this event is.

> ppois(q=6, lambda=1.8, lower.tail = TRUE, log.p = FALSE)
[1] 0.9974306

not sure if ppois is the right one to use and the parameters...

thx much
