Question 694410
according to a transport sector conference in New zealand, 75% of workers drive to work. suppose a random sample of 200 of workers is taken.
---------------------------------------
Binomial Problem with n = 200 ; p(drive) = 0.75
-----
a. What is the probability that between at least 
   135 but no more than 160 drive to work?
P(135<= x <=160) = binomcdf(200,0.75,160)-binomcdf(200,0.75,134) = 0.9527
===============================


b.what is the probability that less than 120 workers drive to work?
P(0<= x <=120) = binomcdf(200,0.75,119) = 0.000001079
==================
