In the theory of general intelligence, it is stated that being good in one intelligence, like math, increases the chance of one being good in another intelligence. Suppose 10% of the people are good at art, and that 40% of the people who are good at art are also good at math. If a person is not good at art, they have only a 30% chance of being good at math. What is the probability that a person who is good at math will also be good at art?
