Suki has 54 rock songs, 92 dance songs and 12 classical songs on her playlist. If Suki’s music player randomly selects a song from the playlist, what is the probability that the song will not be a classical song?
You have to add up all the individual songs, which is 158. Then add up the number of songs that aren't classical, which is 146. Then divide 146 by 158 which gives you your answer.
