you have torn a tendon and are facing surgery to repair it. the surgeon explains the risk to you: infection occurs 3% of such operations, the repair fails in 14%, and both infection and failure occur together in 1%. what percent of these operations succeed and are free from infection?
If portions of the 3% and 14% are not included in the 1%, then:
100% - 3% - 14% -1% = ?
