If Scotland beats Ireland in the Rugby World Cup, the outcome will depend on the number of points Scotland scores and the number of points Ireland scores. Here are the different scenarios that could happen:

• If Scotland wins and scores five points with a winning margin of 21 points or more, and Ireland scores one point, then both Scotland and Ireland will go through. Scotland would top the group with such a winning margin, with Ireland going through in second.

• If Scotland wins and scores five points with a winning margin of 20 points, and Ireland scores one point, then Scotland goes through and Ireland is out.

• If Scotland wins and scores five points, and Ireland scores none, then Scotland goes through and Ireland is out.

• If Scotland wins and scores four tries, but Ireland secures one losing bonus point, then Pool B goes to a tiebreaker, with Scotland, Ireland, and South Africa all finishing on the same number of points.

• If Scotland wins but does not secure a bonus point, and Ireland picks up one or two of their own losing bonus points, then Scotland is eliminated.

• If Ireland wins or draws, then Scotland is out.

• If Scotland wins but does not secure a bonus point, and Ireland scores four tries and loses by fewer than seven points, then Ireland goes through.

• If Scotland wins with a bonus point (by scoring at least four tries) or by denying Ireland a losing bonus, then Scotland goes through.

• If Scotland wins but does not secure a bonus point, and Ireland picks up a losing bonus point of their own, then Ireland goes through.

• If Scotland wins but does not secure a bonus point, and Ireland scores four tries and loses by seven points or more, then Pool B goes to a tiebreaker between Scotland and South Africa, with the team with the superior points difference going through.

• If Scotland wins but does not secure a bonus point, and Ireland scores four tries and loses by exactly seven points, then Pool B goes to a tiebreaker between Scotland and South Africa, with the team with the superior points difference going through.

• If Scotland wins but does not secure a bonus point, and Ireland scores four tries and loses by more than seven points, then Scotland goes through.

• If Scotland wins but does not secure a bonus point, and Ireland scores five tries or more, then Ireland goes through.
