Three questions...

What are the odds (and the math) of flopping exactly 1 pr from two non-paired cards? I've seen anywhere from 27-30%.

What are the odds of making a straight by the river (pre-flop odds, that is) of connectors (87o etc.)?

And for 1-gap connectors?

If it's been posted in the past, please post the link. I couldn't find it.

Thanks in advance.
