The fraction of players who don't stretch and get injured = 4/9.

The frequency tree is shown in the image attached.

The total number of footballers = 45.

The total number of footballers who stretch = 36.

Therefore, the number of footballers who don't stretch = 45 - 36 = 9.

The total number of injured footballers = 10.

The number of injured footballers from the players who stretch = 6.

Therefore, the number of injured footballers from the footballers who don't stretch = 10 - 6 = 4.

The total number of footballers who don't get injured = 45 - 10 = 35.

The number of footballers who stretch and don't get injured = 36 - 6 = 30.

The number of footballers who don't stretch and don't get injured = 9 - 4 = 5.

Therefore, the frequency tree can be shown in the image attached.

The fraction of players who don't stretch and get injured = 4/9.
