Please give the name of the notebook file. I cannot find where this code is in the course. ---

I think I found it: ![image](https://global.discourse-cdn.com/dlai/original/3X/d/f/df27f3649868d4b58250bc20ccdc5901e9321540.png) It’s buried in the “Loaded Dice” programming assignment of C3 W2. You are correct, that variable should be “sum\_of\_rolls”. It is correct in the original version of this course on Coursera, but it is incorrect in the DL.AI Learning Platform version. I’ll notify the course staff.
