If xx is a binomial random variable, compute p(x)p(x) for each of the following cases: (a) n=5,x=5,p=0.2 p(x)= (b) n=3,x=1,p=0.7 p(x)= (c) n=4,x=2,p=0.6 p(x)= (d) n=3,x=0,p=0.3 p(x)= The rates of on-time flights for commercial jets are continuously tracked by the U.S. Department of Transportation. Recently, Southwest Air had the best rate with 80 % of its flights arriving on time. A test is conducted by randomly selecting 1010 Southwest flights and observing whether they arrive on time. (a) Find the probability that exactly 88 flights...
