Question: What is the chance of having exactly three blocks mined within the next 10 minutes? You can assume that a new block is mined every 10 minutes on average.
Hmm. Am not a good mathematics student but I would like to try my best on this.
If 3 blocks was mined 10 minutes, that means each transaction would be mined within 1/10^3 and 0.0027 per transaction.
1/10^3 gotten from the λ and the 0.0027 is 1/10^3
