What are the four fundamental counting rules in the basic concepts of probability?
The fundamental counting principle states that if there are n(A) outcomes in event A and n(B) outcomes in event B, then there are n(A)×n(B) outcomes in event A and event B combined. The order in which the experiments are done does not affect the total number of possible outcomes.
What are counting principles?
The fundamental counting principle states that if there are p ways to do one thing, and q ways to do another thing, then there are p×q ways to do both things.

Who created the numbers we use today?
For example, the Arabic numeral system we’re all familiar with today is usually credited to two mathematicians from ancient India: Brahmagupta from the 6th century B.C. and Aryabhat from the 5th century B.C. Eventually, numbers were necessary for more than simply counting things.
How did the numbers get their shape?
It claims to show why the numerals that we use look the way that they do. Here it is: According to this, the shapes of the numbers was derived from a notation where for each numeral contains its own number of angles. Just by looking at them, you can see quite a number of problems with them.
