Question 1118072
The Poisson Probability(P) Distribution formula is
:
P (x, mu) = (e^-mu)*(mu^x)/x!, where mu=17.6 thefts/hour, e=2.71828
:
a) P (4, 17.6) = (e^-17.6) * (17.6^4)/4! = 0.00000
:
b) P (0, 17.6) = (e^-17.6) * (17.6^0)/0! = 0.00000
:
c) P (x>=20, 17.6) = 1 - summation i = 0, 19 of P(i, 17.6) = 0.31406
