Relevant Textbook: Discrete Mathematics and Its Applications, 7th edition, by Kenneth H. Rosen

(There are some overlaps between this textbook and CS70. It’s more rigorous than CS70 official notes, so I think it helps develop mathematical maturity. Plus, it’s a fun read.)

For probability section, I highly recommend reading the relevant sections in STAT140 textbook
