Has a FIBA World Cup game ever ended 76-47?
Exactly once. On November 30, 2018, Australia beat Iran 76-47, and no FIBA World Cup game before or since has ended that way. When it happened it was a scorigami, the first 76-47 in league history.
That makes 76-47 the 475th most common final score out of 1,178 that have ever occurred in FIBA World Cup. One point away, 77-47 has happened never and 76-48 has happened never.
