Question 603043
In San Francisco, 30% of workers take public transportation daily. Consider a random sample of 10 workers.
Find the probability that at least 3 workers take public transportation daily.
P(3<= x <=10) = 1 - binomcdf(10,0.3,2) = 0.6172
------------------------------------------------------
Find the probability that fewer than 2 workers take public transportation daily.
P(0<= x <=2) = binomcdf(10,0.3,1) = 0.1493
------------------------------------------------------ 
Find the probability that more than 6 workers take public transportation daily.
P(7<= x <=10) = 1 - binomcdf(10,0.3,6) = 0.0106
------------------------------------------------------
find the probability that at most 2 workers take public transportation daily.
P(0<= x <=2) = 0.3828
