Question

Problem 4 Why would one want to use masking MC/DC instead of unique-cause MC/DC? Give a good example of where use of masking MC/DC would be advantageous. Your example should not just be a Boolean function example, think of a real-world case.

Answer 1

Unique-cause Mc/DC- the condition is independently affect a decisions outcome by varying just that condition while holding fixed all other Possible conditions.

Masking Mc/Dc- A condition is independently affect a decisions outcome by applying principle of Boolean logic to assure that no other condition influence the outcome

*masking refers to the concept that specific inputs to logic construct can hide the effect of other input to construct for example, a false 'input to an ANDoperator masks all other input and a true input to an OR operator mask all other input. the masking approache to Mc/DC allows more than one input to change an independent pair
