Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Assuming P(B) = 1/2 and P(G) = 1/2, the expected ratio of boys to girls would be:
B/G = 1.
Explanation:
Suppose 16 families. On their first child there would be 8 boys and 8 girls. From the
8 families that would try again their would be 4 girls and 4 boys. From the 4 families that would try again there would be 2 girls and 2 boys and from the 2 families that
would try again there would be 1 girl and one boy. Form the last family to try again
the chances of getting a boy or a girl is 1/2. So in a larger population than 16 families
half the time they would get a boy and half the time a girl. The relation of boys to
girls end up to be 1 to 1.

This question is based on a false assumption that 23 is not a real number! Well, sorry to disappoint you, but it is a real number and so the question makes no sense!.
How many are prime number in the number system?
Any number that only has one and itself as factors is prime. Therefore, there is an infinite amount of prime numbers. Any number lower than 0 is not possible to be prime.
What is the set of natural numbers?
The counting numbers, which are integers larger than 0: 1, 2, 3, 4, etc. The modern definition often includes the number zero, too, so you have the set: 0, 1, 2, 3, 4...
How do you find prime number factors?
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.
Example: 210
210 Divide by two.
105,2 Divide by three.
35,3,2 Divide by five.
7,5,3,2 Stop. All the factors are prime.
2 x 3 x 5 x 7 = 210
That's the prime factorization of 210.
Why is 200 not a prime number?
Prime numbers are numbers that can only be divided evenly by itself and 1. 200 isn't a prime number because it can be divided by more than just 1 and itself, eg. 10, 20, 100, etc.
What is the last prime factorization number of 8500?
The prime factorization of 8500 is 2 x 2 x 5 x 5 x 5 x 17. If listed in numerical order from smallest to largest, the last number in the prime factorization is 17.
