For every person who has the flu there are 6 people who have flu like symptoms of a doctor sees 40 patients determine approximately how many patients you would expect to have only flu like symptoms

for every 1 person that has the flu then 6 have flu like symptoms

if the doctor has 40 patients then lets guess and check

if 5 people have the flu then 30 have the flu like symptoms and that is 35 so no

and if 6 had the flu then there would be 36 people with flu like symptoms

so there should be from 30-36 people with ONLY flu like symptoms
