A football team carried out a report to
see the impact of stretching on
preventing injury. Of the 45
footballers in the squad 36 stretch
regularly. Of those who stretch, 6 got
injured last year. There was a total of
10 injured players last year.
The results can be presented in a
frequency tree. What fraction of
players who don't stretch get injured?
