To pass a bill to the president, there must be a majority vote in both houses (over 50%). If the president vetoes the bill, it still may pass, except this time it needs a 2/3 majority vote from both houses.
Actually, there are a limited amount of people in the Senate. Anyway, the bill is passed when there are more votes to pass the bill EX: 60 wants bill, 25 doesn't
It takes 218 votes to pass a bill if everyone votes. There are 435 representatives and a majority ( one more than half) of those voting is required to pass a bill.
3/4 votes from the state legislature, house of representatives and senate
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.
2/3 of Senate
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.
A simple majority ( 51 votes if all vote) will pass any bill in the Senate. (Please note that all tax bills must originate in the House.)
A simple majority of votes is required for a bill to pass in the Senate, which is 51 out of 100 senators.
Well, to overrule a veto: 2/3
The Senate can defeat a bill with 51 votes.
