If the father is A positive and mother is O positive what would the child's blood group be?

There really is no saying what the blood group exactly is. But I would say the chance is probably 50% and 50%. But it depends on who's DNA is more dominate in your body.

That depends completely on what recessive gene the father is carrying. We know the mother has only oo, because O is always recessive. Were she to be carrying a gene for any other blood type, she would not be type O because the other gene would be dominate. You carry two genes for the part of the blood type you're asking about. If Dad carries a recessive O, the children will be either type A or type O. If Dad carries a co-dominate A , the children will only be type A because all the genes the father can pass would be the dominate A. The only possibilities for Dad to have for a recessive gene is the co-dominate A or the recessive O.

Where can you buy E. coli bacteria?

You can buy bacteria (and also yeasts, molds, and viruses) from institutions called type culture collections and from some commercial sources that supply high school and university biology classes. Here are some sources for the USA:

ATCC (American Type Culture Collection) http://www.atcc.org This is the authoritative source, but it serves research institutions predominantly and is pretty expensive. Supply of anything to individuals is restricted.

Presque Isle Cultures http://www.picultures.com has a small collection and sells non-pathogenic strains also to individuals.

Carolina Biological Supply also sells a few bacteria including E. coli:

What are the chances of an O negative father and A positive mother have a child?

The chance they will have a child is most likely high unless they use birth control. If the mother were rh-negative, that can sometimes cause complications, though it's usually manageable.
