Q2 [1] Sally is playing a game of which she needs to answer three questions. If her answer the first question (Q1) is wrong, she wins nothing, and the game is over. The probability of answering Q1 correctly is 65%, and in this case, Sally has the choice to leave the game with BD150 or continue the game to answer a second question (Q2). If her answer to Q2 is wrong, she loses all the previous earnings, and the game is over. The probability of answering Q2 correctly is 45%, and in this case, Sally has the choice to earn another BD300 or continue the game to answer a third question (Q3). If her answer to Q3 was wrong, she loses all the previous earnings, and the game is over. The probability of answering Q3 correctly is 30%, and in this case, Sally earns another BD600, and the game is over. Draw a decision tree to represent Sally's problem. What is the optimal strategy to maximize her earnings?
