Charlie’s mother owns a collection of 45 classical music recording . of these, 2/5 were composed by Mozart, 1/5 were composed by Verdi, and 1/3 were composed by Haydn. How many of the cds contain music that was composed by either Mozart or Verdi?
--------
Mozart #: (2/5)45 = 18
Verdi #:: (1/5)45 = 9
Haydn #:: (1/3)45 = 15
-----
# composed by Mozart or Haydn = 18 + 15 = 33
