What is duck worth Lewis method?

Answer 1

The duckworth Lewis rule or the DL rule is a rule that is used to predict the winner of a cricket match in cases where the match cannot be played till a winner is decided. The rule can be applied when some even stops play when the 2nd batting team is playing. Based on the runs to be scored, runs already scored, wickets in hand etc the DL rule comes up with the result predicting if the second batting could have won if the match had proceeded.

An important consideration here is that - this rule can be applied only after both teams have played a minimum of 20 overs each.
