Determining how many random numbers have to be drawn to get a certain sum? (Script)

Hello everyone,

I am trying to write a 'while loop' script that determines how many random numbers have to be drawn from a uniform distribution between 0 and 1 to get a sum greater than 10. I also have to modify the script so it will repeat the experiment 1 to 1000 times until the condition of 'sum greater than 10' is met.

What I do know is that I have to use a 'while loop' and implement the 'rand' function. But I am completely lost on how to get the ball rolling on this one. Any help is much appreciated!

You can use this general structure

initialize some variables
while true
  do some calculation
  if some condition is satisfied based upon the calculations
     break;
  end
end
