    Conditional poisson question

    Hi, can anyone please help me?
    Suppose the number of earthquakes in a given year is a Poisson random variable with parameter lambda > 0. Suppose in addition that each earthquake that occurs has a probability p of being catastrophic (independently of the nature of other earthquakes). Find the expectation and variance of the number of catastrophic earthquakes in a given year.
