In a population of 10,000, there are 5000 nonsmokers, 2500 smokers of one pack or less per day, and 2500 smokers of more than one pack per day. During any month, there is a 7% probability that a nonsmoker will begin smoking a pack or less per day, and a 4% probability that a nonsmoker will begin smoking more than a pack per day. For smokers who smoke a pack or less per day, there is a 10% probability of quitting and a 10% probability of increasing to more than a pack per day. For smokers who smoke more than a pack per day, there is a 9% probability of quitting and a 10% probability of dropping to a pack or less per day. How many people will be in each group in 1 month, in 2 months, and in 1 year? (Round your answer to the nearest whole number.) (a) in 1 month nonsmokers people people 1 pack/day or less more than 1 pack/day people (b) in 2 months nonsmokers people 1 pack/day or less people more than 1 pack/day people (c) in 1 year nonsmokers people 1 pack/day or less people more than 1 pack/day people
