here is a mathematical analogy.

Say you are betting on the flip of a coin. You know that on any coinflip the odds of a head or tell is 0.5.

Say you flip a coin 10 times...how many times will there be heads ? say approximately 5 times.

How about if you flip a coin 100000 times...? you should get
50000 heads right. thats true.

but no where does it say that you wont get 2000 consecutive heads or tells. thats variance for you.

is my analogy correct ??
