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?
