    Red face how can you calculate this probability with limited information?

    Suppose that the probability of suffering from side effects of the H1N1 vaccination is 0.001. If 1000 people are vaccinated, how do you find the probability that
    1. at most one person suffers from side effects?
    2. 1, 2, or 3 persons suffer?

    Hello,

    It's a binomial distribution with parameters (0.001, 1000)

    A Poisson distribution with a mean of 0.001 * 1000 = 1 would also work well here.
