Answer:
Basketball rarely occurs in a draw, considering the amount of points that are scored. Upon there being a draw at the end of regulation, a period of overtime is played, in which a winner is usually crowned. However, some younger leagues might result in a tie (i.e.: elementary and middle school teams).
I also believe that tennis never really results in a tie either.
I have a notion that when the sports are played on a professional level, then a tie barely occurs. The younger, less competitive leagues can result in draws.
hope this helps.
Regardless of the sport playoffs never allow ties.
