If this has been raised before, I am very happy to delete it. Sorry to have bothered you. I am very confused at this point. If this reads like gibberish, it does so because it is.

So, I am a total rook, currently reading the Harrington on Hold em series, playing low stakes MTTs and Sit and Gos. Since he is using ratios, I would also like to compare equity/probability and pot odds as ratios. I understand odds to draw as the likelihood to make my hand, pot odds as the money I could win for the money I pay for a call, and equity as my likelihood to win the hand in a showdown (ignoring fold equity for now). I understand that if I want to bet or call I always need higher pot odds than drawing probabilities or equity. Since I calculate pot odds as ratios, I need equity and drawing probability in the ratio format as well.

My questions:

What is the difference between drawing probability and equity?

How do I calculate equity? For instance, high cards are a 3-1 underdog v low-pair post-flop and 13-10 pre-flop (says Harrington in vol 2). Do I just need to know that?

How do I calculate drawing probability as a ratio with the 2/4 rule?

Where do I find good memorizing equity charts in ratio sizes for the most common hand v hand scenarios pre-flop and post-flop? What should I commit to memory? My equity against a random hand? My equity against the hand I think that has me beat? The equity against common scenarios?

How do I transform an odds against ratio (number of failures per success) to a odds for ratio (numbers of successes)? Which type should I use in general? Harrington uses numbers of failure per successes for drawing probabilities and numbers of successes per failure for equity. An example: Like Harrington says top pair has 82% eq v lower pair or 4.5-1 (numbers of successes I presume). What if I hold the low pair?

How do I transform ratios to percentages and vice versa? I read something re pot odds about this and it makes sense, but eq/probabilities confuse me here.

Thanks, Z
