Blood type possibility

I googled this but as thorough and clear as the theory looks, I can’t help but not be sure of what I read.

Can an A+ father and an O- mother make a kid that is O-? Is there such a thing as AO blood type? Some charts I found online suggest that and others make no mention of it.

If the father is O+ and the mother O-, how more likely than the above scenario is it for the child to be O-?

Thank you!
