For instance, let's assume I have Qc9h in Button and up against BB.
How then would I calculate the equity of my hand against standard BB range?

P.S. I'm into the 10th video of FTGU but I just got frustrated while playing because I'm not able to get an approximate equity to compare with pot odds in my head.
If this is going to be covered in the later chapters, I apologize for jumping the gun.
