Do not take Math 70 with professor Butson. His exams are simple, but his personality, as well as his teaching methodology was very undesirable. His constant condescending attitude towards students when prompted questions or comments is absurd and his tardiness and lack of care, in general, should be enough to worry if your tuition money is going into a worthwhile class. The topics covered in this class, given a standard/beginner background in calculus or probability, should be simple and quite interesting, to be frank, so if there are other math professors to choose from, I would avoid the headache that comes with taking Butson. He would describe himself as a 'sarcastic' person but I'm sure he just says that to make an excuse for whatever backhanded comment he makes to the class. Also, he curves by percentage, so there is a chance that you may be curved downward, even if you score well in his exams.

This professor is probably one of the nicest ones I've had at UCLA (what they say about Canadians is true) BUT he is a bad lecturer. His lectures are super boring and he does not do a good job of breaking down probability/the class materials. His exams are super easy but the HWs/lectures were very confusing. If the exams were as hard as the HWs, many ppl would have not done well. However, 60%+ of the class got an A- or better given how the exams were generally the easiest HW problem out there for a given concept. I'm sure he's changed as a professor but that is how my experience with Professor Butson was during his quarter here in his Math 70 class.
