Question:

Recall that the Poisson with a parameter value of λ = up can be used to approximate the B(n, p) when n is very large and the success probability p is very small.
A box contains 500 electrical switches, each one of which has a probability of 0.005 of being defective. Use the Poisson to make an approximate calculation of the probability that the box contains no m than 3 defective switches.
