Correct quantity in #visualization-of-cosets caption.

Pls, review this one, it seems to me, that there should be three disjoint cosets.

Hi, thanks a lot for your pull request! I see your point, but your suggestion as is doesn't work either, given that I mention only two colors afterwards ("in orange and yellow"). What I meant with "disjoint" is disjoint from the subgroup (in red) and disjoint from one another. (This becomes clearer in the next caption, where I write about "the only disjoint coset".) How do you feel about simply adding an additional sentence, such as the following: "Since the subgroup is also a coset, there are three disjoint cosets overall."? (Here's a link to this section for later reference.)

Oh, you're totally right! Actually I didn't payed enough attention to the end of the sentence with color names. =( I'm slightly color blind, so didn't saw the difference on the picture itself (saw only green and "other", lol), so proposed what seemed to me as a compact improvement.

PS Sorry for delay, couldn't get back earlier.
