I would add a third: the sin of rebellion. Both Adam and Eve ate the fruit, and only Adam failed to guard. But after God demanded explanations from both of them Adam blamed God, and it was only after that when God cursed the ground.

Adam sins by omission in failing to keep the serpent out of the garden.
God says it’s not good for him to be alone so He makes Eve.
Adam sins again by omission in failing to stop the temptation.
Adam and Eve both eat the fruit and “die” in that day; Adam sins by deliberate choice, but Eve by being beguiled.
Adam blames God and Eve.
Eve reports on the serpent’s trickery.
The serpent is cursed because of what he did, and the Savior is promised through Eve’s seed.
God predicts that Eve will follow Adam out of the garden and only then will he rule over her.
God curses the ground because of what Adam did, and drives only him out of the garden.
Eve follows Adam out, as predicted.
Adam was clearly the repeat offender. That’s why Paul puts all the blame on him.
