Given . Find the probability that X is greater than E[X].
x -1 0 1 2 3
P(X=x) 0.35 0.05 0.1 0.3 0.2
Unsure what's asking me there.
thanks for the help!
Well, exactly what they say, I suppose, i.e. they want to know
.
BTW. It's a bit strange that they tell you what is, because from the given values and probabilities of X one can easily determine the expected value.
