## Should have - Could have - Would have

But I have not contacted him since yesterday. Now I am predicting about the result of his driving test. Please help me to correct my following sentences grammatically and their percentage of possibility.

There is no percentage to be allotted to each sentence. To attempt to assign percentages to those sentences would be to completely ignore their grammatical meanings and implications.

If you really wish to have a mathematical perspective then read my response here: Use of subjunctive form. To assign percentages to denote the possibility of an imaginary number occurring in the real domain would be ridiculous.

As I had written, opposed to grammarians' discrete perspectives and pigeon-holing, the grammatical imaginary domain is actually a continuum of modes. He might have passed the driving test.

## Could have, should have, would have

Imaginary possibility towards the outcome an actual event. Imaginary expectation due to outcome of imaginary possibility.

He may have passed the driving test. Unknown outcome of an actual event.

## Past Modals: Should Have, Could Have, Would Have

Imaginary expectation due to unknown outcome. He could have passed the driving test.

Known and actual failure of an actual event. Imaginary expectation of the imaginary success of an actual event. He must have passed the driving test.

Imaginary positive outcome of an actual event. Unknown expectation based on the imaginary positive outcome. He would have passed the driving test. Imaginary possibility of influence that would have resulted in an imaginary success.

Imaginary success based on the imaginary possibility of the influence.

I don't have the actual time to verify the accuracy of the process flows I assigned above, so I might return to correct it. But, the point is, this is the way to assign mathematical meaning to phrases made in a combination of real and imaginary domains. Grammatically, all of these sentences are acceptable. But your percentages of possibility aren't really on target.

You're unsure how he did but it's possible he passed. The percentage of possibility isn't straightforward.

## Could Have, Would Have, and Should Have

It's affected by context and even, if the sentence is spoken rather than written, inflection. This also doesn't express possibility.

In fact, the sentence implies that he failed the test. He is an excellent driver. But his bus broke down on the way and he missed his appointment. Home Questions Tags Users Unanswered.
