WebCDF = Cumulative Density Distribution Function: This tells you the probability of being <= x, so you add up all of the probabilities up to that point. For a continuous distribution, the CDF is the area under the PDF up to that point. You can take the integral, or just figure it out in this case. The CDF always starts at f (x)=0 and goes up to f ...
