The odds on plaw being in Vegas is 1 out of 90.
The odds on both of you being in Vegas at the same time for any particular day is
1/40 * 1/90 = 1 / 3600, which seems really small.
The problem with your logic, I think, is that those are they odds of us meeting on a predetermined given day.
Like, "what are the odds that they will both be on there on January 15th, given the fact that they are each there for 4 and 9 random days, respectively.
But that's not the question. the question is "what are the odds that we will meet on any day, given the above conditions.
