Lesson 5.6 (Udacity) Section 1 - Differential Privacy - Project Varying Noise typo

[LifeBringer]

Hi Andrew,

There was an error with the completion notes for Section 1
first_coin_flip = (torch.rand(len(db)) < noise).float() should be first_coin_flip = (torch.rand(len(db)) > noise).float()

Please see: https://youtu.be/_ByJgx6H0MQ?t=32 for reference.
