    Probability of road accident!

    Hi,

    Need help to solve the probability problem....

    "
    Probability of occuring road accident yearly in road R1 is 10 out of 50, in road R2 it is 1 out of 150, and in road R3 it is 1 out of 1200. What is the probability of happening road accident in either of the road yearly?"

    Many thanks

    Hey Mahmud.

    Hint - Think about finding the probability of the union of events with the union formula.

    Are we to assume that accidents on any one road are independent of accidents on the other roads? Are you asking for the probability of exactly one accident on any one road or at least one accident on any road?
