The probability of finding one of the two defective fuses is:

The probability of finding 2 defective fuses is:

Therefore the probability of rejecting is 0.3117 + 0.026 = 0.3377.
When you square a negative number, the result is positive.
(-4)^2 = (-4)ª(-4) = 16
When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64
Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.
