Delphi: Very simple random : I have this code	

...

    letsdoit(something,'abcd');
    
    letsdoit(something,'asdfasdf');
    
    letsdoit(something,'gagaga');

...
	
	
I want it to be, if possible, just one simple line with the logic like:

> Question 1:

	
	(letsdoit(something,'abcd'))OR(letsdoit(something,'asdfasdf'))OR(letsdoit(something,'gagaga'));
	
so it has 33% chance to choose either of the three. Or if I do 

> Question 2:

	
	(letsdoit(something,'abcd'))OR(letsdoit(something,'asdfasdf'))
	
it has 50% chance to choose the left or 50% chance for the right thing.
	
	

**So in short,** my questions:
	
*Question 1: randomize between the three and only do one thing.
	
Question 2: randomize between two things and only do one.*
