a well-mixed cookie dough will produce cookies with a mean of 5 chocolate chips apiece. 

what is the probability of getting a cookie with more than 4 chips?

Poisson Distribution uses the formula: P(x; μ) = (e) (μx) / x!

e is always a constant number of 2.71828

x is the number you want to evaluate the probability of occurring

μ is the average, or mean.

So, you would use:

P(4;5)=(2.71828-5)(54)/4!

Worked out, P(4;5)=0.559506714934787

SO: the probability of receiving a cookie with more than 4 chips is 0.559506714934787
