Answer:

P(X<3) = 0.01004

Step-by-step explanation:

From the given information:

Consider the application of Poisson distribution $P(X = x ) = \dfrac{e^{-\lambda} \lambda ^x}{x!}$ with the parameter $\lambda = 8.4$ ;

Therefore, we can calculate the required probability as follows:

P(X< 3) = P(X = 0) + P(X = 1) + P(X =2)

$P(X< 3) = \dfrac{e^{-8.4} 8.4^0}{0!} + \dfrac{e^{-8.4} 8.4^1}{1!} + \dfrac{e^{-8.4} 8.4^2}{2!}$

$P(X< 3) =e^{-8.4}( 1 + 8.4+35.28)$

P(X<3) = 0.01004
