>While there are complicating factors, in general, probabilities add linearly. So for the average woman in the US, who lives for 77 years, she therefore has a 1% chance of being sexually harassed during any 1 year of her life.

Obviously the average survey respondent was not 77 years old, so the math here is wrong. Other assumptions we could make: prepubescent and post-menopausal women are not being sexually harassed at the same rate as women of reproductive age.

I think your point would stand with steelman math, so why strawman it?
