[2008] How to achieve true 50/50 chance?

[arsmakman]

I know I'm being quite pedantic here. But, what is the right way to get a true 50/50-chance with a generated random number? Say, to simulate the flip of a coin.

This is what I mean:

Randomize()

If Rnd() > .5 Then Debug.Print("Heads") Else Debug.Print("Tails")
If Rnd() >= .5 Then Debug.Print("Heads") Else Debug.Print("Tails")

Which of these two is the right one?

I know this difference is close to nothing, but I'm doing some calculations on bell curves, in such a way that it requires true 50/50-chance.

Thanks for any help,
Alexander.
