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 1000 randomly selected 21-40 yr old, 50 died from complications. Among 1200 randomly selected 41-60 yr olds, 70 died; among 1100 61-80 yr olds 125 died; and among 1300 81+ yr olds 250 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.
