I posted the following in the Probablility section, but it probably should have gone here instead (please help!):

I'm a beginner and have read SSH and HEFAP. I've read many of the posts on this great site, and decided to read TOP based on all the info I've read. After getting throught the pot odds section, I got myself totally confused and I really thought I had understood this before!

Here's my "practical" question:

I have four to a flush on the flop. To call a bet at that time, do I need pot odds of at least 1.9 or do I need pot odds of at least 4.1?

What if I miss on the turn. What pot odds will I now need?

Thank you.
