Suppose John has a torn tendon and is facing surgery to repair it. The surgeon explains the risks to John; infection occurs in 3% of operations, the repair fails in 14% of operations, and both infection AND failure occur together in 0.57% of operations. What percentage, P, of these operations succeed and are free from infection?
Round to the nearest two decimal places.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
