Question

phi is a subset of every set, it is true or false​

Answer 1

Answer:

FALSE

Step-by-step explanation:

If by 'phi' you mean the empty set, then it is a subset of every set, including itself, as a consequence of the underlying logic, which is classical. So, the standard way of dealing with the usual material conditional holds.

Answer 2

Answer: True as we include phi while writing proper subset of any set
