Do you want the probabilities from the empirical cumulative distribution function? If so, you can get them from Distribution. Here is the CDF Plot in Distribution:

Click the red triangle next to Weight and select Save > Prob Scores. A new column appears in the data table:

I confirm the empirical CDF by plot the new scores against the original variable, Weight:
