    The above must be wrong since the probability of an event cannot be > 1.

    P ( Po Lin ) = 0.6

    P ( Peak ) = 0.75

    P ( Po Lin and peak ) = 0.45

    So P ( Po Lin or Peak )

    = P ( Po Lin ) + P ( Peak ) - P ( Po Lin and Peak )

    = 0.6 + 0.75 - 0.45

    = 0.9

    P(visit Po Lin Monastery)=0.6

    P(visit the Peak)=0.75

    Probabilities(visit Po Lin Monastery or The Peak) = 0.6+0.75 = 1.35
