CDF() публичный статический Метод

The probability distribution of the number X of Bernoulli trials needed to get one success, supported on the set { 1, 2, 3, ...} https://en.wikipedia.org/wiki/Geometric_distribution k trials where k ∈ {0, 1, 2, 3, ...} pmf = 1 - (1 - p)ᵏ

public static CDF ( integer $k, float $p ) : float
$k	integer	number of trials k ≥ 0
$p	float	success probability 0 < p ≤ 1
Результат	float

    public static function CDF(int $k, float $p) : float
    {
        Support::checkLimits(self::LIMITS, ['k' => $k, 'p' => $p]);
        $⟮1 − p⟯ᵏ = pow(1 - $p, $k);
        return 1 - $⟮1 − p⟯ᵏ;
    }
