    Poisson is for defects while Binomial is for defectives. Both are applied for proportions

    Generally speaking, Poisson distribution is based on rate measure (like number of defects per sq cm) whereas binomial distribution is based on proportion measure. But these two distributions are related: Poisson distribution can be simulated by binomial distribtution when the latter has large n and small p (eg. p<0.01). In choosing which distribution you should use, all you need to consider is which of the two distributions best fit your sample data distribution (or transformed sample data distribution).

    It’s p<0.1, not 0.01
