I was wondering if someone tell me how I go about calculating
collision rates for a "key" that is 2 characters (lowercase alpha
only) long?

I realise it's 26x26 but if I generate two random numbers between 1-26
is that all that's involved? So each time I generate this key, I have
a 1/676 chance of a collision?

Thanks for the help
