Do we always normalize the PDF? I was told in discussion for the exponential pdf that we don't normalize because it sums to 1, but that is not the case if we limit the domain from [0,1]

To answer my previous comment, here we are normalizing because we're doing so over x in [0, 2]. In discussion 6 example 2, the interval [0,1] describes the random variable rather than x, so we don't have to normalize, as the interval for x is for x >= 0, which for the exponential distribution is already normalized
