It's always the same result, or sometimes you get the same result twice in a row? Getting duplicates in a row is not surprising - if you flip a coin 30 times, you'll see a lot of HeadHeadHead and TailTailTail.

If you want to get rid of dupes, you'll have to keep track of what the last item chosen was, and pick a new item if you pull a dupe. We could do this with a "do-while" loop.

- (IBAction)hello:(id)sender {
	//"static" means this variable will keeps it value between function calls.
	static int lastChosen=0;
	
	//this is the same
	NSArray *myArray= [NSArray arrayWithObjects: @"Yes",@"No",@"Maybe", nil];
	int length = [myArray count];
	
	int chosen;
	//this is a "Do" loop - it repeats as long as the "while" is true. 
	//we'll keep picking numbers until we get not-a-dupe
	do {
		chosen = (float)random() * length /RAND_MAX;	
	} while(chosen==lastChosen);
	
	//this is the same
	NSString *item = [myArray objectAtIndex: chosen];
	
	//this is how we combine the two strings
	helloLabel.text = [NSString stringWithFormat: @"The item I picked is: %@", item];

	//save the value for the next function call
	lastChosen=chosen;
}
