Let X be a positive variable with E(X) =5 and E(X)^2 =31.25

[Matt Wirtz]

Please find an upper bound for P(X>=10) using Markov's and Chebyshev's

Please state which is which. I'm not very good at stats and this is a homework problem :P

Thanks!

That's where i 'm a little lost on this one. I have no start but i need to learn how to at least. Step by step i guess.

I hope that's somewhat acceptable by your guy's terms :)
