The probability of unlocking the door in the second try = (3/4) (1/3) = 1/4. The probability of unlocking the door in the third try = (3/4) (2/3) (1/2) = 1/4. Therefore, the probability of unlocking the door in at most three tries = 1/4 + 1/4 + 1/4 = 3/4. Example 7.3.6 Web1 Answer. Most classification decision tree algorithms provide both a class and probability. The probability that you see is the number of correct classifications at each leaf. So if at one leaf in your tree you have 1 observation of class A and 3 of class B you will see a probability of .75 for class B and the model will predict class B. city center rva
