Solve the problem involving probabilities with independent events. A spinner is used for which it is equally probable that the pointer will land on any one of six regions. Three of the regions are colored red, two are colored green, and one is colored yellow. If the pointer is spun three times, find the probability it will land on green every time.
A paper bag contains a mixture of three types of treats: 12 granola bars, 10 fruits bars, and 8 cheese strips. Suppose that you play a game in which a treat is randomly taken from a bag and replaced, and then a second treat is drawn from the bag. You are allowed to keep the second treat only if it was thesame type as the treat that was drawn the first time. Determine the probability that you'll be able to keep a cheese strip.
