Sun Country Airlines claims that there is a 0.12 probability that a coach-class ticket holder who flies fre- quently will be upgraded to first class on any flight. This outcome is independent from flight to flight. Joe
is a frequent flier who always purchases coach-class tickets.
(a) What is the probability Joe's first upgrade will occur on the second flight? Show your work!
(b) What is the probability that Joe's first upgrade will occur after the third flight? Show your work!
(c) What is the probability that Joe will be upgraded at least 5 times in his next 20 flights? Show your
work!
(d) Joe will take 50 flights next year. How many times can he expect to be upgraded to first class?
What is the standard deviation? Use the values in a sentence with CONTEXT

Ahigh-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. suppose that the radius r increases at the rate of 0.02 inches per second, and that r = 36 inches at time t = 0. determine the equation that models the volume v of the balloon at time t, and find the volume when t = 360 seconds. v(t) = 4π(0.02t)2; 651.44 in3 v(t) = 4π(36 + 0.02t)2; 1,694,397.14 in3 v(t) = four pi times the product of zero point zero two and t to the third power divided by three.; 4,690.37 in3 v(t) = four pi times the quantity of thirty six plus zero point zero two t to the third power divided by three.; 337,706.83 in3
