    Poisson distribution

    Using Poisson distribution, find the probability that the ace of spade will be drawn from a pack of well shuffled cards at least once in 104 consecutive trials.

    Please help me in solving the problem

    Re: Poisson distribution

    You want P(X>0) where X=number of times ace of spades is picked. This can be modelled with Bin(n,p) and I'm sure you can fill in n and p.

    The Bin(n,p) can then be approximated to Poisson(np) as n is "large" and p is "small".
