How many different pairs can I have from two groups? A company has 8 painters and 12 electricians, and teams can be created of one painter and one electrician. How many different teams can be created?
My best guess is:

$ {8 \choose 1}  * {12 \choose 1}$

but I am unsure if that is correct. If it is, am I also correct in assuming the reasoning is because for each of the 8 painters, they could be paired with any of the 12 electricians?

Its actually just 12*8, as you can have 12 different electricians and for each you can have 8 different painters. So your answer and guess are perfectly right :)
