Are $X, Y$ independent? Does [this](https://en.m.wikipedia.org/wiki/Irwin%E2%80%93Hall_distribution) help? – Dayne Nov 16 '20 at 16:43

1You could apply any of the five methods I describe at https://stats.stackexchange.com/a/43075/919. But are you asking how to find the *joint* pdf of $(Z,T)$ or to find their *marginal* pdfs separately? – whuber Nov 16 '20 at 17:20
