1-random(random()) aka 1-random()*random(),looks slightly skewed toward circumference, and 1-random()^2 looks slightly skewed toward center. If you plot their difference, 1-random(random()) aka 1-random()*random() is empirically skewed slightly larger than 1-random()^2, but I don't know how to analyze it exactly analytically.
