Not sure I get the causal implication with the "so" in your comment.

The diagrams you provided are correct, and ko is correct for the third problem - but I didn't quite get your comment. With 5@2, where are 3 and 4?

Sorry, I meant 3 @ 2. Then White makes the ko-mouth and Black gives atari.

Both possible variations though I think the first has white defending better. Either way white dies.

Problem 3

First tried this variation but the throw in means white lives.

$$B
$$ | . . . . . . . . . .
$$ | . . . X X X . . . .
$$ | . . X O O O X X . .
$$ | . . X , . . O . X ,
$$ | . . . X O 2 . O X .

I didn't think this would work and it didn't

$$B
$$ | . . . . . . . . . .
$$ | . . . X X X . . . .
$$ | . . X O O O X X . .
$$ | . . X , 2 . O . X ,
$$ | . . . X O 1 . O X .
$$ | . X . X O . . O X .

And a couple variations later I came to this conclusion.

$$B

$$ | . . . X X X . . . .
$$ | . . X O O O X X . .
$$ | . . X , 2 7 O 5 X ,
