A safety monitoring system in a chemical plant uses three sensors to determine if a relief valve should be activated:
The digital logic circuit shown below determines the valve activation signal Y Y\,Y based on the inputs from these sensors.

Write a Boolean expression to show how the output Y Y\,Y is calculated from the inputs AAA, BBB, and CCC.
You can use either the Boolean operator words (AND, OR, NOT) or standard logic symbols.
