About Randomness

The only source of all randomness around us is our lack of knowledge.?

The simplest example is tossing a coin. If we know the height of throwing, whether the head or tail was facing us initially, the angular velocity of the flip, how high we threw it, the air pressure and humidity, and many such attributes, then we can know the outcome for sure.

But since we have none of this information, we call it a random process.

Next time, we better be careful while using the word random in any context, as it might reflect our lack of knowledge.
