    problem solving

    a music festival was oragianised to be held on a long weekend(three days) in april at rock bay. on average. on average it rains six days in april in rock bay.

    - so far i have worked out the probability that it rains on a particliar day in aprill which is \frac{1}{5}.

    - it than asks me to find the probabilty that there is no rain rain for three days?

    so what is the pr(there is no rain for three days)?.

    If = \frac{1}{5}" alt="Pr = \frac{1}{5}" /> then Pr(Rain') = \frac{4}{5}.


    So draw a tree diagram for the three days (attached), follow the branches for no rain, and multiply the corresponding probabilities.
