let's say first and code the first symbol here a we have a distribution that's available to us the malls the probability of these symbols I'm gonna say okay 80% chance it's a 2% chance it's B so we're gonna actually map the fact that I have an A to this interval over here it means we landed you can think about the all possible random events that couldn't happen in the world is the ones that lie on the 0 to 0.28 interval that's the event that has happened then when the next a comes in we're going to take that interval that
