In what ways are serial works and music of chance completely opposites? Hypothesize about possible commonalities.

What will be an ideal response?

Serial music and chance are compositional and philosophical opposites. Serialism demands that the composer completely manipulate every detail of a performance, dictating each aspect of tonal and rhythmic nuance. Chance, on the other hand, demands spontaneity in performance, preferring that significant aspects of the performance happen "by chance." With chance, no two performances are alike. Oddly, the two techniques may be difficult to distinguish to the untrained ear. Both tend to have dissonant passages, lack singable melodies, and have no easily detectable formal structure. (Although serialism is highly structured, the structure is not easily heard.) For these reasons, both serialism and chance have lacked popularity with the general public. Interestingly, the composers in both "camps" have not been concerned with the lack of audience appeal.
