v.easy probability question
maybe i'm just tired, but this 'should be' easy question is troubling me!
let , where k is a constant and
what is the value of k for f(x) to be a probability density function?
i'm thinking it could either be -1 or 1? but the next question goes on to ask about 0.5 etc and so i think i'm wrong!
p.s. <= means "less than or equal to".
thanks
