Answer by stanbon(57282)   (Show Source): You can put this solution on YOUR website!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 ======================== Cheers, Stan H.
