Question 819824
Application (Binomial approximation) Based on past experience, the police department of the city of Bowie knows that 50% of the automobiles reported stolen are recovered. In a month in which 10 automobiles are stolen, what is the probability that:
-----
Using my TI-84 to get these answers::
===== 
a.) 3 or more of the stolen automobiles will be recovered.
P(3<= x <=10) = 1 - binomcdf(10,0.5,2) = 0.9453
------------------------------------------------ 
b.) Less than 2 automobiles will be recovered.
P(0<= x <=2) = binomcdf(10,0.5,2) = 0.0547
----------------------------------------------- 
c.) Between 1 and 2 automobiles will be recovered.
P(1<= x <=2) = binomcdf(10,0.5,2)-binompdf(10,0.5,0) = 0.0537
