I am a non-major interested in data analysis and artificial intelligence. I applied for the course because probability and statistics were essential. I looked for a book that suited me, but I couldn't find it, so I applied for the course after watching the preview of this lecture. It is definitely not an easy subject, but it is easy to follow because it only covers the key points step by step. It is good because I can cool my head and check what I learned in theory by occasionally practicing coding. I highly recommend it to those who are interested in probability and statistics.
