it sounds like that this lecturer is saying https://youtu.be/qzn8Bz4rzLk?t=1923
two people with the same credit score may have a different probability of default.
this seems to be not grammatical.

I guess the following one (my version) would be more appropriate,

two people with the same credit score may have different probabilities of default.

is my version better? or both versions are grammatical?

Firstly, I agree that he is saying:
two people with the same credit score may have a different probability of default

Secondly, I'd have to agree with you that your version is grammatical and his isn't. But in informal usage it's reasonably idiomatic and most native speakers would not bother to pick him up on that :roll: Nevertheless, you are right.
