<p>You have the basic structure of the essay right–intro stating position, three example paragraphs, and conclusion. My criticisms are that the language is a bit too simple, and the second example doesn’t really involve unexpected, chance events (a better literary example might be the things that happen in Garp, if you’ve ever read that). As for your third example, while it theoretically shouldn’t make a difference, I would question the wisdom of using a controversial example. Your essay will be graded by human beings, an inherently subjective process.</p>
