Answer:
The answer is 9/11.
Step-by-step explanation:
To find the answer you'd first add up how many patients you have:
80+10+20 = 110.
Now find out that how many patients are taking a real drug, which is represented by 80+10 = 90.
So, the probability of a patient NOT getting a placebo is 90/110
Simplified would be 9/11
Thus the answer is 9/11....
