Probability Values for Each Section
Part 1 – Science in The Quran = “1 in 1 billion”
Part 2 – Literary Quality of The Quran = “1 in 10 million”
Part 3 – Prophecies Within The Quran = “1 in 1 million”
In order to produce a single probability value which represents the probability (chances) of one person being able to accomplish all three of the above aspects of the discussion, you simply multiply them. If you're not familiar with this concept, it is simply an established mathematical rule that has been applied. I will try to explain it using a simpler analogy, shown below –
Lets say “1 in 2” people of the general population are male, and “1 in 4” males are brown eyed. Now, in order to find the probability of finding a male with brown eyes within the general population, all you do, is multiply both probabilities as follows: 1/2 * 1/4 = 1/8 (which equates to a “1 in 8” chance of finding a brown eyed male in the general population).
Mathematicians prefer to state the probability value as a decimal, in this case that would be “0.125” (1/8). It is also well established that probability values closer to the value of one are more likely to occur than those furthest from one. If a value of one is obtained, this means that it is a certainty, if a value of zero is obtained this means it is impossible.
Using the above method, the values obtained in my discussion were calculated in order to produce a single probability value.
Firstly, using words:
(one/one billion)*(one/ten million)*(one/one million) = one/ten thousand billion billion
Secondly, using numbers:
(1/1 000 000 000)*(1/10 000 000)*(1/1 000 000) = 1/10 000 000 000 000 000 000 000
= 0.0000000000000000000001 (in decimal form)
This equates to a “1 in ten thousand billion billion” chance of this event occurring.
