probability

Let us consider the following number:- 172.9998105

On average, only one randomly generated number out of 2638 randomly generated numbers will be this close to a perfect WHOLE NUMBER.

Question:- How is this calculated?

Answer:- We take the number 0.9998105

This number is (1.00000 minus 0.9998105) = 0.0001895 from a perfect whole number.

A randomly generated number could be 0.0001895 greater than a perfect whole number, or it could be 0.0001895 less than a perfect whole number. Because there are TWO options here, we multiply by 2.

0.0001895 x 2 = 0.000379

In that case, the probability that a randomly generated number will be as close to a perfect whole number as the number 172.9998105 is = 0.000379

The statistical odds against the chance occurrence of an event occurring is the reciprocal of the probability of that event occurring. This makes the odds against chance occurrence

1 ÷ 0.000379 = 2638

In that case, on average, only one randomly generated number out of 2638 randomly generated numbers will be as close to a perfect WHOLE NUMBER as the number 172.9998105 is.
