Suppose there is a 10.4% probability that a randomly selected person aged 20 years or older is a smoker. In addition, there is a 19.8% probability that a randomly selected person aged 20years or older is male, given that he or she smokes. What is the probability that a randomly selected person aged 20 years or older is male and smokes? Would it be unusual to randomlyselect a person aged 20 years or older who is male and smokes?The probability that a randomly selected person aged 20 years or older is male and smokes is(Round to three decimal places as needed.).

The local weather forecaster predicts that there is a 12% chance of rain on each day next week. Assuming his prediction is accurate and that the chance of rain in a given day does not depend on the chance of rain in a different day, what is the probability it will rain on at least 4 of the days next week?

The weather in a particular town in the Pacific northwest is classified as either good, indifferent or bad. If the weather is good on a particular day, the probability it will remain good the next day is only 11%, and there is a 45% chance it will be indifferent. If the weather is indifferent on a particular day, there is a 20% chance it will become good, and a 42% chance it will become bad. If the weather is bad on a particular day, there is a 48% chance it will be bad the next day, and a 21% chance it will become indifferent. Construct the stochastic matrix that models this problem.
