What is the outcome for the vast majority of bills that are assigned to committees in the texas legislature?

Vast majority of bills is removed.

Explanation:

When legislator introduces a bill, during a regular session (where more than 7000 bills can be introduced), after it's reading the bill is assigned to a standing committee. This is where the majority of bills die. If a bill survives the committee stage, it is then being sent to the Calendars Committee to be schelduled for a debate. A bill must have a two-thirds majority to pass in the Senate. Then the bill is sent for a governor to action - he can make it into law, it can be allowed to become law without governor's signature, or it can be vetoed.
