3Does "at any time" mean "in any second"? (If it means "in any millisecond", for instance, the answer will be rather different.) – 2011-06-03

1The answer is $1$ if $p = 0$, else it is $0$. – 2011-06-03

1Dan, I guess you are right. ShreevatsaR's comment explained it. – 2011-06-03

1Dan, what would be the "right" hypothesis to consider for this problem (instead of "at any time, a dog has the probability of p to bark")? – 2011-06-03

0Fine, I'll drop the word "hypothesis" from my vocabulary. – 2011-06-03

0I was just suggesting that in mathematics we shouldn't assume time is quantized in any particular way. But actually I was wrong for the same reason! :) – 2011-06-03

0Dan, that's not how stochastic processes in continuous time work. – 2011-06-03

0Is my humor misunderstood. or is it not funny? After I rigorously inspect it I'll know for sure. – 2011-06-03

1I was referring to your first comment. The humor in the second one is appreciated. – 2011-06-03
