Aritificial Intelligence is atually studied in different disciplines such as Computer Science, Computer Engineering, Electrical Engineering etc. I guess the type of math you´d be using would depend on the kind of exposure you´d be getting. For example, I´m studying electrical engineering, and we deal mainly with pattern recognition in AI. For example, image recognition, voice recognition etc. In such courses, you´d need higher level statistics and probability in addition to linear algebra. For example, speech recognition utilizes hidden markov modelling which is pretty high level probability and stochastic processes.
