Please, can someone help me to prove this formula?
$$ P\{\,H ≥ k.R^a.(J(R)+N)\,\} = E_R\{\,exp(-k.R^a.N/q). E[ exp(-k.R^a.J(R)/q)|R]\,\}$$
With H is exponential distribution with parameter q.
P is the probability. J(R) is a function of R.
E is the expectation.
I hope that the formula is clear enough.
Many thanks in advance :)
