Thank you for the dictionary definition—I never would have thought of that!
However, the dictionary presents man’s definition of chance, not God’s definition. To God, there is no chance. Given that, even the random, chance occurrences that are part of evolutionary theory are all part of God’s plan.
God's definition is ours since He gave us the mind to understand the world around us. He created our rational mind, our logic, our reason. Every definition we conceive has been pre-ordained by God.
You are correct in saying the to God, there is no chance. Simply because we see it as chance does not mean it is so to the Master. Consider this, were we to be able to account for every occurance, every reaction to some action, then there would be no such word as 'random' or 'chance'. God has this ability being Omniscient and Omnipotent. Part of His job description.
