    Atleast 14 do not means 13 or less do,not 11 or less.The compliment of atleast 14 is atmost 13.

    Question about poisson distributed variables

    The sum of 2 poissons is obviously poisson just like the sum of 2 binomials is binomial,ur reasoning is flawed,if X ε Poi(λ) and Y=X+X,THEN Y ε Poi(2λ),it follows quite simply evn by general reasoning.

    My suggestion is that you should try the moment generating function technique,ofcos u will need the theorem on limiting mgfs,bt it is the easiet way,or do a transformation

    Probability of a random number - seems impossible

    Mathman is right,getting a kazillion 9s is not equiprobable to getting an even distribution,i.e it can only happen in 1 way while the numbers can be evenly distributed a number of different ways e.g. the probability of 6000 6s in 6000 throws of a die is not even close to being equal to the...
