泊松分布计算器

用 $$$\lambda = 11$$$ 和 $$$x = 10$$$ 计算泊松分布的各项数值。

平均值：$$$\mu = \lambda = 11$$$A。

方差：$$$\sigma^{2} = \lambda = 11$$$A。

标准差: $$$\sigma = \sqrt{\lambda} = \sqrt{11}\approx 3.3166247903554$$$A.

$$$P{\left(X = 10 \right)}\approx 0.119378060228025$$$A

$$$P{\left(X \lt 10 \right)}\approx 0.340510642465661$$$A

$$$P{\left(X \leq 10 \right)}\approx 0.459888702693687$$$A

$$$P{\left(X \gt 10 \right)}\approx 0.540111297306313$$$A

$$$P{\left(X \geq 10 \right)}\approx 0.659489357534339$$$A
