| Question : |
Is it true that some people believe that Odd Numbers are
Lucky ? |
Answer : |
|
According to Stanislaw Ulam, the originator of the lucky numbers,
odd numbers are lucky and he discovered it through the following process.
|
We start with a list of numbers one through twenty-five :
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25
|
The first number > 1 is 2, so remove out every second number from the list :
1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25
|
The first number > 1 is 3, so remove out every third number from the list :
1, 3, 7, 9, 13, 15, 19, 21, 25
|
The first number > 3 is 7, so remove out every seventh number from the list :
1, 3, 7, 9, 13, 15, 21, 25
|
|
Numbers remaining after this procedure has been carried out completely are called lucky numbers.
