They are close to a given big number for every given large number? In addition, how many prime numbers are there that are smaller than that number?
An excellent approximation of the average distance between primes near any big integer n is given by the formula ln (n). It’s amazing how accurate this estimate is in this situation.
In order to demonstrate this, the following table displays a range of the first 15 million primes, which are divided into groups of one million. The average distance in the range between primes, as well as an estimate of the average distance, are shown in the table. The estimate is based on the natural log of the average of the biggest and smallest primes in the range of possibilities. For example, the ln((256,203,221+275,604,541)/2) function is used for the 15th group of a million primes.
Starting with integrating the average distance estimate of ln, we may find out the number of primes that fall within a certain integer (n). This will give us the total of the average distances between prime numbers up to any integer n, which is useful information.
Which function f(n)=ln(n) has the largest integral? Remember that integration by parts informs us about the following:
Integration of f(n)*g'(n) dn = f(n)*g(n) – integral of (f'(n)*g(n) dn = f(n)*g(n) – integral of (f'(n)*g(n)
In this case, let f(n) = l(n) and g'(n) = 1. Then f'(n)=1/n and g(n)=n are obtained. As a result, the integral of ln(n) will be ln(n)*n – the integral of ((1/n)*n) = ln(n)*n – n = n*(ln(n)-1) = ln(n)*n – n = n*(ln(n)-1) = ln(n)*n – n = n*(ln(n)-1) =
In the range of integers from 2 to n, we may get the average distance between primes by dividing n*(ln(n)-1) by n, which is the average distance between primes. This is equal to ln(n)-1.
If we divide the number n by the average distance between primes, we obtain the average number of primes beneath the number n, which equals n/(ln(n)-1), which is equal to n/(ln(n)-1).
In order to demonstrate this, the following table lists the number of primes found under different big integers, as well as the projected value for each prime. Please forgive the accuracy of 15 significant digits, which is the maximum that Excel will allow. Someone, please create a spreadsheet that is capable of handling more data.
Introduction to the Topics of Fire and Ice
When playing pai gow (tiles), the Borgata in Atlantic City offers a side wager known as “Fire and Ice.” If all four tiles in the player’s hand are the same color, the wager is successful.
My thoughts on Fire and Ice are summarized in the following table. The house edge in the lower right cell is 14.50 percent, as seen in the bottom right cell:
- Pai gow is played with 32 tiles, which are colored as follows: • 5 all red tiles • 13 all white tiles • 14 tiles of a mixture of colors
- Winning is determined by the player’s four tiles.
- If all four tiles are red, the Fire and Ice bet pays off at a ratio of 1000 to 1.
- If all four tiles are white, the Fire and Ice bet pays off at a ratio of 35 to 1.
- If any other occurrence occurs, the Fire and Ice team will be defeated.
