Just trying to figure cc for negative values If x is greater than or equal to -2 , I would assume because it includes -2 to cater for that we add 0.5 to get -1.5 ? In the Cmp the answer is -2.5 ? Doesn't that mean if we put a number line on a distribution we are missing out the 2? Thanks
You need to compute: P(X >= -2) This equals P(X > -2.5). Note this includes -2 within the range. If you say this equals P(X > 1.5), this does not include -2 any longer !
