Using an Excel worksheet, what is the formula for the percentage of wins for a team. Example 2 wins and 1 loss equals what percentage of wins?

Played 3, Won 2 Lost 1... =sum(Won/Played)*100

2 wins divided by 1 loss = 5o% which is the amount of percentage in which 1 loss equals to wins.

You take the number of wins and divide it by the total number of games played. In this example, 2/3 = .666
