There are two reasons for this: * Firstly, a spherical ball will bounce more predictably. Some games use non-spherical balls (such as American Football or Rugby) and part of the game is the non-predictability of the bounce. * The other thing is that if you inflate anything it will tend to form a sphere; with a sphere the pressure inside the ball is equal throughout the inside of the ball - this is why when bubbles are blown, the are always spheres. It isn't that a ball is round. It's that we call a round thing a ball (or sphere).

What are Things that are round?

Things that are round include everyday objects like balls, coins, and plates, as well as natural forms such as fruits like oranges and apples. Celestial bodies, such as planets and stars, also exhibit round shapes due to gravitational forces. Additionally, many mechanical components, like gears and wheels, are designed in a circular form for functionality. Round shapes are often associated with symmetry and balance in both nature and design.

What looks like flattened balls?

Flattened balls can refer to various objects or phenomena, such as pancakes, which are round and flat, or certain types of sports balls that have lost air pressure, making them appear deflated. In nature, some fruits, like certain varieties of apples or tomatoes, can also exhibit a flattened shape. Additionally, planets like Jupiter and Saturn are often described as oblate spheroids, appearing slightly flattened at the poles due to their rotation.


What is the probability of choosing 3 red balls and 2 black balls out of a bag which contains 5 red balls 2 green balls and 4 black balls?
