zhège zhōumò wǒ kěnéng méiyǒu shíjiān
这个周末我可能没有时间。
This weekend I might not have time.
wǒde huídá kěnéng cuò le
我的回答可能错了。
My answer might be wrong.

And if we say 不可能, it suggests that having no possibility. For example,

xiàozhǎng bù kěnéng bú rènshi nà ge nǚrén
校长不可能不认识那个女人。
The school principal can't not know that woman.
nàbiān nà ge nánrén bù kěnéng shì wǒ zhàngfu
那边那个男人不可能是我丈夫。
That man over there cannot be my husband.

Grammar 2: Questions with 吧 in Chinese · HSK 2

We’ve learned 吧 used as a Modal Particle before, where we can use 吧 at the end of a suggestion to soften the tone.

In today's lesson we’ll see some examples of using 吧 as a Question Particle, at the end of a sentence to ask a question.

Usually we say a statement, followed by Question Particle 吧 to ask about the listener's opinion about the statement. We are usually trying to get a confirmation.

Questions with 吧 have a tone of guessing and reckoning. It suggests that we’re not sure about what we’re saying and are just asking whether it is like that or not. So by using 吧, we’re not actually asking the question, we’re really just saying a statement but just don’t want to make it sound like we’re 100% sure about it.

The structure goes like this:

STATEMENT + 吧？

For example,

nà ge nǚrén shì xiàozhǎng ba
那个女人是校长吧？
That woman is the school principal, right?
tā hái méi huídá wǒmen ba
他还没回答我们吧？
He hasn't answered us yet, right?

吧 can be used together with 可能 as well. For example,

tā kěnéng cuò le ba
他可能错了吧？
He (is) probably wrong?
nǐ kěnéng hái bù zhīdào ba
你可能还不知道吧？
You probably don't know yet?
