Weekly Challenge Problem
In a Quidditch game, a team tallies 10 points when it scores a goal with the quaffle. To score a goal, a chaser must throw the quaffle through 1 of 3 hoops. Malfoy is taking a penalty shot for Slytherine, and Ron is the keeper. Malfoy has an equal chance of putting the penalty shot in any of the 3 hoops; however, he misses every 4th penalty completed. If Ron guesses the correct hoop, he saves the penalty shot. What is the probability that Malfoy scores the penalty shot?
