A company has two R&D teams, A and B. To compare their R&D levels, the results of randomly selected new product developments from these two teams in previous years are as follows:  
(a, b), (a, $$\overline {b}$$), (a, b), ($$\overline {a}$$, b), ($$\overline {a}$$, $$\overline {b}$$), (a, b), (a, b), (a, $$\overline {b}$$),  
($$\overline {a}$$, b), (a, $$\overline {b}$$), ($$\overline {a}$$, $$\overline {b}$$), (a, b), (a, $$\overline {b}$$), ($$\overline {a}$$, b), (a, b)  
where a, $$\overline {a}$$ represent team A's success and failure in R&D, respectively, and b, $$\overline {b}$$ represent team B's success and failure in R&D, respectively.  
(I) If a team successfully develops a new product, it scores 1 point; otherwise, it scores 0 points. Calculate the average scores and variances of the new product developments of teams A and B, and compare their R&D levels;  
(II) If the company arranges for teams A and B to each develop the same product, estimate the probability that exactly one team succeeds in R&D.
