It's the same p.d.f. as before: f(x) = 8/(x^3) where x>2
first question is what is F(6 given 4<X<8)
my main issue with this question is that I thought you couldn't find the probability of individual points with continuous distributions. Is this a trick question and the answer is zero?
I divided f(x) by Pr(4<X<8) which altogether was 128/(3x^3), the antiderivative of that is -64/(3x^2), so I just plug 6 into that even though it results in a negative number. I'm beginning to think its not asking for a probability it just wants me to plug in 6 but I'm not sure.
and my second question using the same p.d.f. is What is E[Max(Xsub1,Xsub2,Xsub3)]
I don't know what the X's with the subscripts are supposed to mean or what the question is even asking.

I need help with 2 more questions relating to the last problem I posted
