WebAssuming this is the x-axis. So it's a very important thing to realize. Because when a random variable can take on an infinite number of values, or it can take on any value between an interval, to get an exact value, to get exactly 1.999, the probability is actually 0. It's like asking you what is the area under a curve on just this line. WebApr 14, 2024 · Data ingestion.
