1. ## approximation

X is hyp(1000, 50, 0.4)
Y is Po(16) and Z is Po(3)
X, Y and Z is independent.

a) which approximation have 2X-Y-Z=?

b) determen with following of a) one approximation value of k so
P(2X-Y > Z+k)=90% ?

What distribution do you think hyp(1000,50,0.4) represents?

(I will assume Po(n) represents the Poisson distribution with mean n)
