Multiple Choice

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. $( x ! = x \cdot ( x - 1 ) \cdot ( x - 2 ) \cdot \ldots \cdot ( 3 ) ( 2 ) ( 1 ) )$
