Suppose we have a code: 4457
If these numbers are randomly drawn what are the odds of drawing those numbers?
Here's my approach:
The available numbers range from 0123456789 and there are four columns, minus the numbers which were drawn gives: 1/(10^4-4)~0.01%
Now what about the odds of drawing the exact sequence 4457? Would I simple multiply the above figure by 0.25?
I'm not really sure about either solution. I included my initial reasoning to compare it with the actual solution method.
