PT71.S3.Q24 (Cameras and Concrete) - Does the Video have the Contrapositive Mixed Up?

The 7sage video says that the stim. says:

S -> (U or C)

thus, S -> (C -> U)

But this doesn't seem right?

Shouldn't the contrapositive instead be: (U and C) -> S ?

This question is in general very frustrating and confusing, but I need to understand how J.Y. came to the conclusions he came to.

    Thats not a contrapositive. He's saying in the world of S, you must have U or C. Therefore in the world of S, if you don't have C then you have to have U.

    If A, then B or C.

    Therefore C
