let X have an exponential pfd with B=500. so f(x)=(1/500)exp(-x/500) with x from 0 to infinity.
a. compute P(X>500)
b. compute the conditional probability
again thanks!
a. thats what my book says, but somehow i remember a way of figuring this out without doing an integral...
b. thats exactly what i thought, unfortunately it says nothing further than that. any ideas what it could possibly mean?
keep in mind this book is absolutely terrible
