What are the chances of dying when you take ecstasy?

mk so some friends of mine want me to take one hit of "Mollie" with them tomorrow night. I dont know if I should do it, because you know, I dont want to die. On urban dictionary i read that mollie is pure ecstasy. please no drugs are bad lectures, I just want to know what the chances of me dying when i take it are. ive never taken ecstasy before.
(if you can include sources thatd be fantastic)
