A Cricket Team needs to score 7 runs in last 2 balls to win the match.What is the probability that the team wins the match?

Assume that:

-There were no wide balls or no balls bowled in these 2 balls.

-No wicket has fallen in these 2 balls.

-No overthrows or extra runs were scored in these 2 balls.

- In case if run(s) are scored on any of these 2 balls it can only be one of these values: 1,2,3,4 & 6

This also implies that it's quite possible that zero runs are scored on a particular ball
