Using FractionalChance for experiment to run only 1 out of 100 times

$chance = new FractionalChance();
// Setting experiment to run 1%, 1/100 times, default 1 out of value sent to setProbability
$chance->setProbability(100);
// Explicitly setting probability to 1% or 1/100 chance
$chance->setProbability(100, 1);
$experiment = (new Scientist\Laboratory)
  ->experiment('experiment title')
  ->control($controlCallback)
  ->chance($chance)
  ->trial('trial name', $trialCallback)
  ->matcher($matcher);

Using FractionalChance for experiment to run 33.3%, 1/3 of the time

$chance = new FractionalChance();
$chance->setProbability(3,1);
$experiment = (new Scientist\Laboratory)
  ->experiment('experiment title')
  ->control($controlCallback)
  ->chance($chance)
  ->trial('trial name', $trialCallback)
  ->matcher($matcher);
