An urn initially contains one red and one blue ball. at each stage, a ball is randomly chosen and then replaced along with another of the same color. let x denote the selection number of the first chosen ball that is blue. for instance, if the first selection is red and the second blue, then x is equal to 2. (a) find
p{x> i},i≥1
. (b) show that, with probability 1, a blue ball is eventually chosen. (that is, show that
p{x< [infinity]}=1.)
(c) find e[x].

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
