    You can easily go to point A, find point E and follow the arrow's directions to figure out how many different ways you can go.

    A > B > E
    A > B > D > E
    A > C > D > E

    Then for the next part; multiply the probabilities of each of the sequences above, and add your results together.

    5/12
