Yes, in the Drake equation, the events may be independent. I am not sure about the independence of fl, fi and fc.
Do they even teach math (or perhaps it is basic logic) in France anymore? Seriously.
Note the phrase, "probability of life elsewhere". In particular note the key word, 'elsewhere'.
Now, pray tell, how exactly does the fact that life exists here prove that P, which refers to the probability of life elsewhere, is not zero?
So, sorry my little French friend, but the uniform distribution that you want is indeed [0,1], not (0,1] .
