Team 1 failures  =  2

 

Total Failures by all teams  =  10

          Failures by Team 1    =    2

          Failures by all teams  =  10 

 

          Proportion of Team 1 failures to Total failures  =  2/10 

 

          2/10  =  20%

Chris, please check your line 2.

 

2 + 3 + 5 = 10  total failures
