Re: Re: •Re: Selecting random records from an array

He is creating a throttle or valve with the grep function, allowing only a certain stochastic percentage of @input applicants through the valve into the accepted @subset.

Think of it as a lottery: anybody who flips a coin twice and gets a "heads" in either flip will win. That could be everyone, it could be nobody, but the odds are that about 75% of the players will win.

I know. merlyn's Original post had `my @subset = rand(75) <= 100, @input;`, which wasn't using grep at all. Apparently he's updated the node.
