Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
The number of people who took the remedy = 45
Now, 88% of 45 = [tex]\frac{88}{100} \times 45 = 39.6[/tex]
and 39.6 ≈ 40
So, out of 45 people, the remedy worked on total 40 people.
Now, let E: Event of people being cured by cold remedy
Favorable outcomes = 40
[tex]\textrm{Probability of Event E} = \frac{\textrm{Total number of favorable outcomes}}{\textrm{Total outcomes}}[/tex]
or, [tex]\textrm{Probability of people getting cured} = \frac{\textrm{40}}{\textrm{45}}[/tex] = [tex]\frac{8}{9}[/tex]
Hence, the probability of cured people in who took the remedy is 8/9.
