Is わけない the shortened version of わけがない?


Hi I would like to know if わけない is the shortened version of わけがない / わけはない (it
is not possible that)

I am pretty sure it is but it would be nice if I had some confirmation. I
would like also to know what nuances it bring (if any)

> あんな状況でいきなり連れてこられて、持ってる **わけない** でしょう？

> here !




According to Tae Kim (of course, not always the best of sources) and Jisho it
is.

Tae Kim (from [Hypothesizing and
Concluding](http://www.guidetojapanese.org/learn/grammar/reasoning)):

Also, Imabi uses it interchangeably in his (their?) [Wake + Negation
article](https://www.imabi.net/wakenegation.htm):
