Question 1195019
.
There are 4 white and 1007 black marbles in a basket and we pick the marbles one at a time 
and return them to the basket. Lets say S1000 marks the amount of white marbles picked after 1000 tries. 
Use Poisson theorem to find the probability of picking a white marble. 
Do you have any advice where I could find a tutorial on Poisson? Thanks!
