5 days are possible Schedule are there to play hockey on Wednesday or Monday or both.
Let’s solve the problem with the help of the Set theory.
Let Set A be the given days Bob only plays hockey.
Set A = { Tuesday, Wednesday, Friday}
Let Set B be the given days Ron only plays hockey.
Set B = { Thrusday, Sunday}
So, (Set A \cap Set B ) = 0 (Null Set) which denotes days in which both of them play together.
(Set A \cup Set B ) = { Tuesday, Wednesday, Thursday, Friday, Sunday} > which denotes days in each week at least one of them plays hockey.
Set theory is the branch of mathematical logic that studies sets, which can be informally described as sets of objects. All sorts of objects can be grouped into sets, but set theory as a branch of mathematics deals mainly with mathematics as a whole.
