Two buddies, Zeke and Bubba, plan a squirrel-hunting trip. Bubba is a better shot than Zeke. How much better? Bubba is 2-times a better shot than Zeke.

Upon seeing a squirrel, Bubba and Zeke raise their rifles and simultaneously shoot at the squirrel. Assume that Bubba shooting the squirrel and Zeke shooting the squirrel are independent events, and that the probability of Zeke shooting the squirrel is 0.25.

Part (a) What is the probability that the squirrel will be shot?

Part (b) What is the probability that both Zeke and Bubba will miss the squirrel?

Part (c) If the squirrel is shot, what is the probability that Zeke shot the squirrel?

Part (d) If only one of the two buddies shot the squirrel, what is the probability it was Bubba?
