If X is the number scored in a throw of a fair die,show that the Chebyshev's inequality gives
Where is the mean of X,while the actual probability is zero.
I don't see where the trouble could be here. Where are you stuck?
You should know how to calculate the standard deviation of the number scored.
So solve for k and then substitute this value of k into the right hand side of the Chebyshev inequality given here: Chebyshev's inequality - Wikipedia, the free encyclopedia
