Determining Independence of Events A and B Using Complements

This lesson teaches how to determine if events A and B are independent using complements. It reviews conditional probability and independence, emphasizing strategic use of complements to simplify calculations. The lesson includes examples, such as calculating the probability of rolling dice and analyzing the impact of sunscreen on sunburn probability. It concludes that different SPSF levels do not significantly affect sunburn probability, highlighting the importance of understanding complements in probability.
