Can you take the contrapositive here?

If some clouds are black and it's humid, then it will rain.

I have it notated as follows:
C<-s->B + H -> R

My question is - can you even take a contrapositive of this statement?
And if so, is it the following:

/R -> /H or C->/B

In other words:

If it is not raining, then it means either it is not humid or all clouds are not black...

Am i correct in thinking this?

Hi there, "Some" statements can be read both ways. You don't need a contrapositive for the Some statement below, specifically.

Refer to the lesson link I posted below.

So in this case, C (Some) B and H -> R

The contrapositive should be: R-> H or ~~C Some B~~

If it is not raining, then it means either it is not humid or some clouds are not black.

This is how far as my understanding goes - If someone else would like to correct me, they're most welcome.
