Given the fоllоwing dаtа, аnswer the fоllowing questions. Hint: Start by putting the data in a Contingency Table. In a study of smokers and non-smokers, the following data was obtained. Among 100 randomly selected 18-22 yr olds, 30 smoke and 70 do not. Among 110 randomly selected 23-30 yr olds, 25 smoke and 85 do not, and among 120 31-40 yr olds, 20 smoke and 100 do not. What is the probability of randomly picking someone from the study who is 31-40 yrs old and smokes? [31andsmoke] What is the probability of randomly picking someone from the study who is 18-22 yrs old or is a non-smoker? [18orNS] What is the probability of randomly picking someone from the study who smokes, given they are 23-30 yrs old? [Sgiven23] note: answer in decimal form and round to 3 decimal places

Given the fоllоwing dаtа, аnswer the fоllowing questions. Hint: Start by putting the data in a Contingency Table (note: this data is not real). In a study of people who contracted the Covid-19 virus, the following data was collected. Among 3000 randomly selected 21-40 yr old, 120 died from complications. Among 3200 randomly selected 41-60 yr olds, 200 died; among 3400 61-80 yr olds 300 died; and among 3600 81+ yr olds 500 died. What is the probability of randomly selecting someone from the study who is 21-40 yrs old and who died from the virus? [21died] What is the probability of randomly selecting someone from the study who is 41-60 yrs old or who survived the virus? [41survived] What is the probability of randomly selecting someone from the study who survived the virus, given they are 81+ yrs old? [survG81] note: answer in decimal form and round to 3 decimal places.
