Question 1195322
since the number is proportional to time, it would be 19/60 per second, and that is the specific Poisson parameter.
For a given second, it is e^(-19/60)*(19/60)^1/1!=0.2307
For two seconds, it would be parameter 38/60 or 19/30
this is e^(-19/30)*(19/30)^2/2!=0.1065, less likely because need two relatively uncommon events in a second rather than 1, but there is a little more time, just not enough to deal with the fact the number has doubled.
