Answer:

Logic with the use of Truth Table

Step-by-step explanation: a) Oleg is a math major= P; Oleg is a economic major=Q; Oleg is required to take math 362=R; Oleg is not required to take 362=←R

b)i) Oleg is a math major or Oleg is an economic major:

     P║ Q ║ P∨Q

     T     T       T

     T      F       T

     F      T       T

     F      F       F

ii)  Oleg is a math major, then Oleg is required to take Math 362:

    P║  R  ║  P∧ R

    T     T         T

    T     F         F

    F     T         F

    F     F         F

iii) Oleg is an economic major or Oleg is not required to take Math 362:

    Q║   ←R   ║  Q ∨ ←R

    T        T              T

    T        F              T

    F        T              T

    F        F              F

c) It is valid because Oleg can only take Math 362 since Oleg is a math major, therefore, it follows that, R ∧ ( P ∨  Q) is valid.
