Answer :
Sure! Let's go through the steps to find the probability that a person was satisfied with the knee surgery, given that they had knee surgery.
1. Understand the Information Given:
- We have a total of 95 patients who had knee surgery.
- Out of those, 70 were satisfied with the surgery.
2. Calculate the Probability:
- To find the probability that a person was satisfied given that they had knee surgery, you divide the number of satisfied knee surgery patients by the total number of knee surgery patients.
- Probability = (Number of satisfied knee patients) / (Total number of knee patients)
- Probability = 70 / 95
3. Convert to Percentage:
- Convert this probability into a percentage by multiplying by 100.
- Probability as a percentage = (70 / 95) * 100
- Probability = 73.7% (rounded to the nearest tenth of a percent)
Therefore, the probability that a randomly selected person was satisfied given that they had knee surgery is 73.7%.
So, the correct answer is option B: 73.7%.
