Answer:

99.91%.

Explanation:

For Salt Lake City, the probability that there will be fire damage is:

5% = 0.05

Therefore, the probability that there will be no fire is:

99.95% = 0.9995

For Cleveland, the probability that there will be fire damage is:

4% = 0.04

Therefore, the probability that there will be no fire is:

99.96% = 0.9996

To calculate the probability that none of the production facilities will damaged by fire, we simply multiply both probabilities thus:

0.9995 X 0.9996

= 0.9991

The answer is therefore:

99.91%
