X എന്നത് ഒരു പോയിസ്സോൻ ചരമാണ്. P(X=2)=2/3 P(X=1) ആയാൽ P(X=0)=.........

A1/e²

B1/e

Ce43e^{\frac{-4}{3}}

De43e^{\frac{4}{3}}

Answer:

e43e^{\frac{-4}{3}}

Read Explanation:

P(X=2)=eλλ22!P(X=2) = \frac{e^{-λ}λ^2}{2!}

P(X=1)=eλλ1!P(X=1)=\frac{e^{-λ}λ}{1!}

P(X=2)=23P(X=1)P(X=2)= \frac{2}{3}P(X=1)

eλλ22!=23eλλ1!\frac{e^{-λ}λ^2}{2!}= \frac{2}{3}\frac{e^{-λ}λ}{1!}

λ2=23\frac{λ}{2}= \frac{2}{3}

λ=43λ=\frac{4}{3}

P(X=0)=eλλ00!=eλP(X=0)= \frac{e^{-λ}λ^0}{0!} = e^{-λ}

=e43=e^{\frac{-4}{3}}
