What potential pitfalls should be considered when calculating probabilities for damage in a PHP game?

When calculating probabilities for damage in a PHP game, one potential pitfall to consider is ensuring that the probabilities add up to 100%. This means that the total probability of all possible outcomes should equal 1. If the probabilities do not add up to 100%, it can lead to inaccurate calculations and unexpected behavior in the game. 

// Example of calculating probabilities for damage in a PHP game

$probabilities = [
    'low' => 0.2,
    'medium' => 0.5,
    'high' => 0.3
];

$totalProbability = array_sum($probabilities);

if ($totalProbability != 1) {
    // Adjust probabilities to ensure they add up to 100%
    foreach ($probabilities as $key => $value) {
        $probabilities[$key] = $value / $totalProbability;
    }
}

// Now the probabilities add up to 1
