WebStep 1: Construct the probability tree showing two selections, There are 9 balls to begin with, reducing to 8 after the first selection, as shown below, The chance of selecting a red ball for the first selection is \dfrac {4} {9}, then with one red ball removed, the second selection is \dfrac {3} {8} and so on…. WebTree diagrams may represent a series of independent events (such as a set of coin flips) or conditional probabilities (such as drawing cards from a deck, without replacing the cards).
