### Marginal Distribution for Random Variable

Let X1 and X2 be two independent random variables having Poisson Dist. with parameters mew(subscript1)=2 and mew(subscript 2)=3 respectively. Then the marginal distribution for the random variable X2 is : a.) h(X2) = e^-2*2^Xz/X2!, x2=0,1,2,3,... b.) h(X2) = e^-5*5^Xz/X2!, x2=0,1,2,3,... c.) h(X2) = e^-3*3^Xz/X2!, x2
