Conclusions:
I All mails being updates is a possibility.
II. No update is a mail.
Some mails are chats. There is a possibility that all mails are chats. All updates are chats. So, if mails is a subset of updates, which in turn is a subset of chats, the conditions still hold true. So, conclusion I follows. Conclusion II is not necessarily true as there might be some intersection between mails and updates.
