In the U.S. Senate, 51 votes are needed to pass a bill on the floor. A bill can also pass on a tie vote (50 - 50 or otherwise), as the Vice President will then cast a vote to break the tie. A bill cannot even reach the floor for a vote, however, if it is the subject of a filibuster unless there are 60 votes for cloture (which will allow a floor vote on the bill). In the U.S. House, 218 votes are needed to pass a bill on the floor.
2/3 of the voters need to vote to pass it.
There are 100 United States Senators. A majority of the Sentate is needed for a bill to be passed. However, if there is a filibuster, then it requires 60 votes to overcome the filibuster, and then it takes a majority of the Senate to pass a bill.
