\textbf{Given:}

\textsf{In a Poisson distribution, mean is 5}

\textbf{To find:}

\mathsf{P(X=0)}

\textbf{Solution:}

\boxed{\textsf{Concept used:}}

\textsf{The probability mass function of poisson distribution is}

\mathsf{P(X=x)=\dfrac{e^{-\lambda}\,{\lambda}^x}{x!}}

\mathsf{Here,\;\lambda=5}

\mathsf{P(X=0)}

\mathsf{=\dfrac{e^{-5}\,5^0}{0!}}

\mathsf{=\dfrac{e^{-5}(1)}{1}}

\mathsf{=e^{-5}}

\implies\boxed{\mathsf{P(X=0)=e^{-5}}}
