Your question is:
i think the first 3 exaple pictures are wrong(i think)...you have a GS and FD so is about 3:1 for a call not 4:1 is it???
This question applies to the strategy article:
https://www.pokerstrategy.com/strategy/various-poker/basics-implied-odds/
in the third example, you hold 8♥:7♥: and the flop is J♥:T♥:2♠:
You have 8 heart outs, and 3 9s as outs -- plush the 9♥: for the straight flush.
Total is 13 outs. There are 47 unknown cards, so you have 13 outs, and 34 bad cards, so your odds of improving are 2.6:1
So yes, you are correct that the example the 4:1 figure is wrong.
Let's assume though that the person who created the example missed the fact that there is a gutshot as well as a flush draw. Let's also disregard the fact that this is really weak flush draw!
With only the 9 hearts as outs, the odds are then 38:9 or 4.2:1
The idea of these examples is to show how the calculation is done.
In this example, I think it is overly optimistic to assume your flush draw will be the winning hand if it hits.
