What is the probability that a csv file of 1000 lines is processed correctly if only 10 are checked?

Question

Probability theory

A csv file with 1000 lines has been processed.
10 lines were randomly checked - they were processed correctly.
What is the probability that the entire file is processed correctly?
Update:
Is there any way to estimate the number of successfully processed rows? There are clearly more than 10 of them, because if there were only 10 of them in the file, the probability of choosing exactly these 10 correct lines out of 1000 would be extremely small. Or the fact that the rows are randomly selected does not give anything and you can just as well select the first 10?

Answer 1

Not enough data.
We need the probability of an error in a single line.
This probability is not deduced in any way from the 10 tested rows. More precisely, we can, of course, say that the probability of an error is 0%, but since there are more than 10 rows, there is a possibility that we made an erroneous conclusion.
To calculate the probability of an error in a row, you need to check all 1000 rows. Or this probability should be simply given in the condition of the problem.
Here is a similar example for you. I roll the dice 2 times. The first time the number 1 fell out. What is the probability that the number 1 fell out both times? At the same time, you do not know how many faces the bone has - 4, 6, 8, 10 or more.
