Final answer:
The United States Supreme Court has 9 justices, and if no presidential candidate receives the majority of Electoral College votes, the President is chosen by the U.S. House of Representatives.
Step-by-step explanation:
The number of justices that preside on the United States Supreme Court is 9. There are currently 9 justices on the Supreme Court, but this number is not fixed and can be changed by Congress. Each justice is appointed by the President and confirmed by the Senate. They serve lifetime appointments and are responsible for interpreting the Constitution and making important legal decisions.
If no presidential candidate receives the majority of the Electoral College votes during an election for the United States President, the President of the United States will be chosen by the U.S. House of Representatives. The House of Representatives uses a system called a contingent election to determine the President. Each state delegation in the House gets one vote, and the candidate who receives the majority of votes from the state delegations becomes the President.
