pick me a random number for me to buy lottery ticket
user
Sure! How about the number 47? Good luck!

Oh sorry I should have been more specific, I need a 6 digit number followed by two letters. The winnings are shared by everyone with the same number. So can you give me a number that has the least chance of being chosen by someone else?
user
will do. here you have a number that i suspect no one will choose. 867530NI.

My friend is also going to buy a lottery ticket, can you generate another random number for her?
user
How about 976495HZ?

I should warn you that like most people I might not be very good at choosing high quality random numbers.  You might be better served by visiting a site like random.org which is dedicated to providing high quality randomness.
