我想你漏了 Least 這個字
Least squares approximation method = 最小平方逼近方法 (最小二乘逼近法)
The prime numbers between 1 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97. (The number 1 is not considered as a prime number)
There are 25 prime numbers between 1 and 100
The probability is 25/100 = 1/4
Hence the probability of prime numbers occurring between 1 and 100 is 1 in 4.
100 numbers (10^2) - From 1 to 100
~ Probability = ¼
1000 numbers (10^3) – From 1 to 1000
- Probability = 1/(4 +2) = 1/6
1 in 6 chance of a prime in the numbers from 1 to 1000
10000 numbers (10^4) - From 1 to 10000
~ Probability = 1/(6 +2) = 1/8
1 in 8 chance of a prime in the numbers from 1 to 10 000
100000 numbers (10^4) - From 1 to 100000
~ Probability = 1/(8 +2) = 1/10
1 in 10 chance of a prime in the numbers from 1 to 100 000 etc.
如此類推.
