sum of the probabilities is at most 1, so it cannot be 42 ans 4.2. 1000 is a just a simple size and it could 1001. Jay is correct the answer is 0.042.

I think 42 is right. Cause the question is What is the sum of the probabilities that the model assigns to all the filers.
for each filers, the probability is 0.042, so the 1000 filers sum will have 42.
