Solve the problem.
-A grocery store normally sells 8 jars of caviar per week. Use the Poisson Distribution $P ( x ) = \frac { 8 ^ { x } e ^ { - 8 } } { x ! }$ to find the probability (to three decimals) of selling 3 jars in a week. $( x ! = x \cdot ( x - 1 ) \cdot ( x - 2 ) \cdot \ldots \cdot ( 3 ) ( 2 ) ( 1 ) )$
A) 0.057
B) 0.019
C) 0.086
D) 0.029

Question

Quizplus · Accepted Answer

The probability of selling 3 jars is calculated using the Poisson formula: $P(3) = \frac{8^3 e^{-8}}{3!}$. This evaluates to approximately 0.029.

Solve the Problem P(x)=8xe−8x!P ( x ) = \frac { 8 ^ { x } e ^ { - 8 } } { x ! }P(x)=x!8xe−8​

Solve the Problem $P ( x ) = \frac { 8 ^ { x } e ^ { - 8 } } { x ! }$
