I have noticed this sometimes. I remember that when I entered 0.8848, it was marked wrong but after sometime, I received an e-mail from the Brilliant staff that it was mistakenly marked wrong. I think they forgot to change the correct answer but gave them points who submitted the correct answer. Brilliant staff should look into this. Pranav Arora · 4 years ago

There was a numerical issue with the answer to this problem originally. It was corrected and everyone got their appropriate points, but that's why there is the discrepancy between the image and the user solution. 0.885 is the correct answer. David Mattingly Staff · 4 years ago
