For example is the Lottery, ERNIE or a throw of dice totally random.

No

I believe Ernie uses something called a random number generator which over a great deal of time will begin to show patterns of numbers.

The lottery machines can be predicted as to which balls will come out if you could work out all the maths involving air flow, speed of rotation, weight of each ball, diameter of tube etc.

As for dice, there is a one in six chance of throwing the number of your choice. (1-6)

There may only be a one in six choice for the number appearing on a die but, if the die is perfectly symmetrical, the order in which different numbers appear for consecutive throws is truly random.

Most things in life are truly random.

Good someone has understood the question at last.

"The lottery machines can be predicted as to which balls will come out if you could work out all the maths involving air flow, speed of rotation, weight of each ball, diameter of tube etc."

Surely the same principal has to be applied to dice unless they are perfect (perfection being something we have failed to attain) and thrown on a "perfect" surface.

"if the die is perfectly symmetrical" which it cannot be. Any other takers on this.

Randomness has some similarities to Chaos theory. Have a look here and see if you agree!!

john bunyan, your reference to the "chaos theory" as interesting as it is has little to do with what I was asking.

Talking about lotteries, we have about £100 in Premium Bond Ernies, which we got from the very early days, and never had any wins yet.

Usually get a Lucky Dip from Camelot, and I often wonder if the numbers generated are likely to be in the low winner category selection. Get the very occasional £10 win, with the very very odd extra ball win, usually on a low pay-out day?.

To have understood the question is more important than knowing the answer I was taught.

Let's have another think on the question, can anything man made create a truly random number.
