sinplyfy 12 out of 20 to 3 over 5 then the rest of people are the amount that will get the flue(2 out of 5)

Answer 2

12/20 got the flu and recovered in 3 days.

8/20 got the flu and didn't recover in 3 days. (20 - 12 = 8)

8/20 = 4/10 = 2/5

The probability that a randomly chosen patient will not recover in 3 days is a 2/5 chance.
