### Probability and Statistics: Conditional Probability---**Scenario:**Suppose there is a 10.1% probability that a randomly selected person aged 35 years or older is a smoker. In addition, there is a 13.4% probability that a randomly selected person aged 35 years or older is male, given that he or she smokes. What is the probability that a randomly selected person aged 35 years or older is male and smokes? Would it be unusual to randomly select a person aged 35 years or older who is male and smokes?---**Question:**The probability that a randomly selected person aged 35 years or older is male and smokes is (Round to three decimal places as needed).**Follow-up Question:**Would it be unusual?- Yes- No

. Assume that 75 percent of the students at the university have taken 4 years of high school math. Of those with four years of high school math, 80 percent plan to major in science.

In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household) Among the respondents, 208 answered "none", 285 said "one", 358 said "two", 149 said "three", and 129 responded with four or more. A survey respondent is selected at random. Find the Probability that his/her household has four or more cell phones in use. Is it likely for a household to have four or more cell phones in use? Consider and event to be unlikely if its probability is less than or equal to 0.05.
Suppose there is a 11.9% probability that a randomly selected person aged 35 years or older is a jogger. In addition, there is a 15.9% probability that a randomly selected person aged 35 years or older is female, given that he or she jogs. What is the probability that a randomly selected person aged 35 years or older is female and jogs? Would it be unusual to randomly select a person aged 35 years or older who is female and jogs? The probability that a randomly selected person aged 35 years or older is female and jogs is (Round to three decimal places as needed.).
