Para a média e o desvio padrão fornecidos, a calculadora encontrará várias probabilidades para a variável aleatória e vice-versa: para a probabilidade especificada, ela encontrará os valores da variável aleatória.

If $X$ is a normally distributed variable with the mean $\mu=$ and the standard deviation $\sigma=$, then
$P(X \leq$ $)=?$
$P(X \geq$ $)=?$
$P($ $\leq X \leq$ $)=?$
$P\left ( X \leq ? \right) =$
$P\left ( X \geq ? \right) =$
$P \left( -? \leq X \leq ? \right) =$
Skip input, if you don't need it.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your input: calculate $P\left( -? \leq X \leq ? \right)=0.95$ with $\mu=0$ and $\sigma=1$

$P\left(-0.975 \leq X \leq 0.975\right)=0.95$
