The mathematically correct answer A is more useful if you take everything that's been said very literal and you want to figure out probability in the sense of population statistics. Which is more useful in say, social research.
The casually correct, more intuitive, answer B is more useful if you want to know whether Linda is more likely to be a feminist relative to others.
The reason that many people would go for B probably has to with an evolutionary advantage of viewing probability in the world that way.
The defect of being inclined to answer A is that you get in trouble when you're technically correct but completely missing the point. For example, your partner is very upset that you "never take the trash out", and you respond with "that's a lie. that is not true. I took the trash out last month once.". You're technically correct, but you're not doing your relationship any good.
I think that if you're dealing with large complex problems, you'd probably need people who are actually different in these things to address both sides.
