What chance is there when it comes to the laws of probability?  If you answer, "Not much!" you are right, because the laws of probability are carefully defined and calculated mathematically.  There is no real element of chance whatsoever.  For example, take a coin and toss it in the air.  If the coin is perfectly balanced, it has a one-in-two chance of coming up heads, right?  Now, what chance is there in its coming up heads twice in a row?  The odds are one in four.  Again, what chance is there of the coin coming up heads three times in a row?  If you answer, "A chance in eight," you are right, and I suspect you have given this matter some thought on previous occasions.
