Independent Random Varaible

hi...i have two poisson random variables x(a) and x(b-a), meaning two
poisson non-overlapping random variables. i need to show that they're
indepdent of each other. i'm really new to matlab...how do you go about
doing so? i know i need to show that
f(x(a),x(b-a)) = f(x(a))*f(x(b-a))--joint density is equal to the
product of the densities of two random variables. but i don't know how
to show that in matlab. i've generated the poisson varaibles but i
don't know how to get the probability/density function
f(x(a),x(b-a)), or f(x(a)), or f(x(b-a))---when you have the random
variables how do you get a probability function for different ranges
meaning probability function from 0 to time a and from a to b or 0 to
b, etc. may be someone knows another way of proving two poisson random
variables are independent. help is much appreciated. thanx
