One day while Neil was cleaning offices he a revelating thought...
|
|
|
|
 | |  |
| I wonder what is the probability of one of the 300 offices being occupied after closing hours? | |
 | |  |
|
 |
|
|
|
Just then Isabella entered her office...
|
|
|
|
| | |
| Hello i overheard your question and i know the answer | |
| | |
|
 |
|
|
|
|
|
|
| | |
| Since 70% of offices are occupied after closing hours then the remaining 30% of non-occupied offices are can be found using the complement rule | |
| | |
|
|
| | |
| What's the complement rule? | |
