Say every 10th reply to a youtube comment the user will get a dollar. You can only reply once with each account.
Millions of people start replying to this youtube comment so they can "earn" a dollar.
Some people even make alts. You are one of them. You decide to make 9 alts, adding up to 10 youtube comments.
Question: What is the probability that you will get a dollar if you reply with your 10 accounts?

Are you asking
A dollar exactly
Or
At least one dollar
?
>>
>>8567333
65.132% for at least one dollar
34.868% for exactly one dollar
34.868% for nothing

>>8567345
edit:
38.742 for exactly one dollar
>>
How did you get that?
>>
F=Binom(10,0.1)
calculate probability of P(F=0), P(F=1), and 1-P(F=1)

You're assuming that every reply is independent of every other reply (i.e. that people won't be counting and replying more furiously when it gets near the 10*n reply)
The problem is not well specified enough to have a definitive answer
