I am have trouble with a question, and how exactly each given part of this question relates to getting the answer.
1. The problemb]
Assume that N,X1, X2...are independent.
Let P(N = k) = qk-1p , k[tex]\geq1[/tex], p+q = 1
and let X1,X2,X3,...be iid with a common pdf
f(x) = { [tex]\lambda[/tex]e-[tex]\lambda[/tex]x, x[tex]\geq0[/tex]
{ 0, x[tex]\leq0[/tex]
*e is raised to the power of 'negative lambda times x'
What theories and concepts should i be familiar with to answer this question? I have studied the chapters up to the ones dealing with Random Variables, as well as Continuous Random variables, yet this question is still not within my reach of solving, or even understanding for that matter. How do i use the given information to create a cdf?
