two dice are tossed together and the bigger of the 2 numbers is recorded. If A represent the event ' bigger number is 4 ' , B represent the event ' the bigger number is odd' , find P(A) , P (A U B)..

i found P(A) , but not P(A U B). i am going to use the complement rule which P (A U B) = P(A) +P(B)-P(A n B) , but there's no P (A n B ) for this question... how should I proceed?
