How do I find more 50/50 chances? (some examples shown)

I wanted to run a function 50% of the time, so I was able to do this:

tickcount % 2 = 0

I was also able to use:

unixtime % 2 = 0

Are there other things that I could use, too?

Essentially, I want to run several functions, each with a randomness factor (of 50%), but I want them all to run randomly from each other - which means I can't use tickcount % 2 each time etc...

Any ideas for a newbie? Am I over-complicating something really easy?

So you want to "toss a coin" and if it's "heads", then you run the function, correct?

The easiest way is to use condition choose(0,1)=1

If you need a 20% chance for example, then use random(100)<20

OMG, I have used 'choose' so many times for other things. I cannot believe I forgot about this!

Many thanks!
